All you can eat restaurants make you unhappy writes Alice Robb:

• In one experiment economists found that the higher the price that people pay for the same food at an all you can eat restaurant, the more they eat.
• However since all you can eat restaurants charge an upfront flat fee the amount of consumption shouldn’t vary by the price paid for entry.
• But people are susceptible to the ‘sunk cost’ fallacy, where they feel that if they pay more they somehow have to make it ‘worth’ more.
• In fact those who ate more ultimately enjoyed their meal less as they overstuffed themselves.
• Thus at all you can eat restaurants it’s possible the more you pay the less happy you’ll be with your food.
