Restaurants may need to have price information ready – even if diners don't want it
Restaurants rarely disclose their food pricing methods, but various models exist. Some fish markets offer cooking services, where customers pay only for the cost of cooking. Buffets and food by weight restaurants have fixed prices, while some restaurants in tourist locations charge exorbitant prices for certain services, such as cutting birthday cakes. Tipping also plays a role in restaurant pricing, with digital payment systems making it easier for customers to add tips. Restaurants may need to provide explanations for their prices as the cost of commodities continues to rise.
