A buffet car (British English) or café car (American English) is a passenger railroad car, where food and beverages can be purchased at a counter. It offers a lower level of service than a dining car (also called a restaurant car in some regions), where passengers are served at tables, but requires fewer staff, reducing operating costs.

Some buffet or café cars include a seating area where passengers can consume their purchases. Typically, passengers are not allowed to eat or drink items brought from elsewhere. On trains without a seating area, passengers are expected to return to their seats to consume any onboard purchases.
