Why is hotel restaurant buffet company Better?

Written by Christopher Qian

Red Lobster, famously, once canceled its “Endless Crab” buffet after losing over USD 3.3 million.​ While this may seem shocking to many, from an economics perspective, such a case should be the norm. What restaurants face when opening a buffet is an issue of adverse selection – when one party (the customer), uses private information (the capacity of the customer’s own stomach), to the counterparty’s (the restaurant’s) disadvantage.​ This theory could explain Red Lobster’s failure to correctly anticipate the costs to the restaurant per consumer and why buffets, in general, should not exist.

 Adverse selection occurs because consumer appetites are varied. For each consumer eating above the average portion expected by restaurants, the restaurant needs other consumers to eat below the average to balance their costs.​ However, rational consumers with small appetites should order cheaper a-la carte options with smaller portions as that is all they need to be full. Based on this logic, only consumers eating enough to be worth the average, or above the average price would want to eat at the restaurant. As a result, restaurants would have to raise their prices, which in turn drives away another portion of their consumers and so on. As seen, this creates some form of a positive feedback loop that would eventually lead to buffets serving only one person: the single biggest eater in the area. A similar phenomenon to the one described above has been observed by Akerlof in the health insurance market: Health conditions of insurance applicants fell, leading to increasing insurance premiums. In a world of homo economicus, buffets should not exist, much less be profitable, yet the buffet industry in the United States rakes in around USD8 billion in revenue each year. 

So how do buffets exist at the scale they do today?

Adverse selection is conditional on one party having an exploitable advantage. One hypothesis is that consumers cannot accurately gauge their appetite due to the existence of cognitive biases. Slovic, Griffin and Tversky suggest that incompatible stimuli and responses can lead to errors in judgement.​ In the context of this investigation, it is unlikely the consumer has been full on whatever they are about to eat in the buffet due to the abundance of options. Hence, the stimulus (food that filled one’s stomach in the past) and response (the amount of buffet food needed to fill one’s stomach) are incompatible and hence consumers’ estimates for their appetite will be error-ridden. 

However, if we assume consumers incorrectly estimate their appetite, consumers will revise their beliefs of their own appetite if they believe they are not maximizing their utility such as if they feel they overpaid for their meal. As consumers begin to frequent the same buffet they will begin to learn from their past visits and derive a more accurate estimate of their appetites, giving them the informational advantage outlined above. Assuming cognitive bias is the main cause of buffets’ profits, they would require a constant stream of new consumers in their region, meaning these restaurants would be most successful in hotels or other tourist areas where there aims high turnover of new consumers. However, buffets can still be seen in many areas where these conditions are not met, such as in Ann Arbor at the Wolverine Sushi Bar which serves all-you-can-eat sushi from Thursday to sunday. 

Perhaps the existence of buffets could be explained by other types of utility generated by its unique characteristics. 

If we assume a restaurant serves two categories of substitute goods: the buffet meal and an a-la carte option and for any portion eaten at a buffet, there is an equally sized a-la carte option. As the two goods fill the consumers up the same, we can infer that they can be priced similarly. An assumption in the adverse selection problem proposed in the introduction is that these two goods cost the same to produce. However, in reality this is not the case. Buffets are not made to order and hence can be prepared en-masse, allowing restaurants to exploit economies of scale leading to huge cost savings. Furthermore, buffets reduce the demand for waitstaff and kitchen staff. As a result, the two goods comparable in price and level of filling can cost restaurants drastically different amounts.

On the consumer side, consumers usually enter a buffet expecting to eat more than usual. While ordering a-la carte, consumers may aim to order an item where the portion size is most fitting to their own appetite in order to maximize their utility from the meal. For those going to buffets however, consumers are shown to engage in behaviors that can lead to over-eating (Thompson). As a result, it can be inferred that consumers will be willing to pay more for a buffet meal than what they would usually be willing to spend on an a-la carte meal as they are eating more. As consumers are willing to pay more, firms are able to increase revenue. 

Furthermore, consumers may in fact value a buffet meal more than an a-la carte option. Research conducted by Professor Koc of Bahcesehir University shows that people tend to prefer salads that they create themselves from a salad bar over a virtually identical salad served by the restaurant. This example of an illusion of choice shows how consumers can assign higher utility to picking their own combination of items in a buffet rather than ordering from a comparatively more choice rigid menu. As such, consumers may in fact value a buffet more, and their willingness to pay. 

As demonstrated above, buffets may in fact be cheaper to produce for restaurants but more valuable in the eyes of consumers. Hence, consumers could feel satisfied eating a certain portion of food that is profitable for the restaurant too, allowing there to be return customers who may eat below the average portion. 

Even as Red Lobster was forced to close down its endless crab buffet, there are still a plethora of buffet restaurants open in America. They pose an interesting economic question and lend a unique insight into the complexity of the human psyche outside the bounds of traditional economics.

A buffet restaurant follows a system of serving meals in which the food is placed in the public area where the diners serve themselves.

Buffet restaurant system is a common thing nowadays whether it is a wedding, corporate event, birthday party, or tourist hotels everyone prefers to have a buffet system.

It is generally preferred by a bigger group of people i.e a family, colleagues or friends. It helps people in a group who wants to eat different things and is also cost-effective, as it provides great variety of food options in a fixed price.

For a restaurant, these buffets can attract a huge crowd to their restaurant and expect a higher bill checkout value.

But just like everything else in life, this too has its pros and cons.

Benefits of having a Buffet Restaurant:

1. Cost effective

When you implement a buffet system in your restaurant your staff members don’t have to take the responsibility of taking the orders and serving the food to the customers. This saves a lot of cost and resources for you in hiring an efficient waiting staff.

Buffet system also works great way to utilize your inventory, you can clearly see what inventory you have the most and make sure to utilize it in your buffet items. Food wastage will also reduce your food costs significantly.

Buffet system is also cost-effective for your customers as they get a variety of options in little money which wouldn’t be possible if they would have ordered the items individually.

2. Variety of options

We established earlier that in the buffet system there is a lot of variety of options available. As a restaurant owner, you can strategize the dishes according to the inventory available.

Moreover, you can also introduce new dishes and experiment with flavors in the buffet to see the customer’s reaction.

If a lot of people opt for that dish in the buffet then it will help you to make a decision whether it can be sold individually on the menu or not.

3. Low customization

Buffet systems are much less fussy than normal dining… at least to some extent!

When it comes to the buffet system the customers already know that there will be less customization. So requests like make it spicier, make it sweeter, mayo on the side, etc will be out of the picture.
Elimination of such requests actually smoothens the flow of operation and staff can focus on providing customer satisfaction.

Your restaurant chefs will also be at ease as they won’t have any dishes returning back for alterations.

4. Inventory friendly

As the buffet system in your restaurant optimize the inventory you have you will save a lot of money by buying the raw materials in bulk and also be eligible for heavy discounts.

Your staff will also have to spend lesser time doing inventory. And you will also see a much lesser raw material food wastage in your kitchen which will eventually help you in reducing your food costs.

Now that we’ve covered the good parts about having a buffet system in your restaurant let’s see the disadvantages that you might face

Disadvantages of having a Buffet Restaurant:

1. Staff attrition

When it comes to the buffet system, yes you won’t need a lot of staff members taking orders and serving plates but your staff members will have some extremely exhausting hours of buffet services such as refilling dishes, maintaining hygiene standards, attending children who are part of a group, talking to the customers, making sure that everything runs smooth, coordinating with the chefs back in the kitchen and so much more.

The chef and their team will also be exhausted making such a huge quantity of food in an extremely short window. Some dishes can be prepared in advance but it will still require heating up and presentation while other things are being prepared from scratch.

Staff attrition can be extremely high in restaurants that follow a buffet system. Therefore, to keep the staff morale high and keep them motivated to serve each day as pleasantly as yesterday you need to implement a good incentive and reward system.

2. Food wastage

One of the biggest disadvantages of having a buffet system in place is the food wastage it brings with it!

All food items on the menu that day are prepared in huge quantities however you cannot 100% predict how much of that item will be actually consumed by the customers.

Most of the time, customers tend to overstuff the food on their plates which ends up in the trash. This is not just unethical but will also increase your food costs over time affecting your overall restaurant profits.

There are no rules or regulations on the amount of quantity that the customers can put up on their plates but you can always make your customer aware of the food wastage and the ecosystem!

3. Maintenance of quality

Running a buffet restaurant requires proper processes and management in place. The kitchen layout, floor plan, serving table, and most importantly the quality of the food needs to be top-notch!

While dealing with such a huge order and continuous demand for a variety of food, mishaps are very likely. Therefore, you need someone to quality to assure the food and services to avoid any kind of negligence.

Once your buffet restaurant earns a good reputation in the eyes of certain customers they will be returning again and again as it will become a sort of family ritual.

Hope this helps you in deciding whether a buffet restaurant is a right fit for your business model or not.
