It depends on the class of the car. All first-class seats (1B, 1C, 1P) include hot meals. Some passengers of the second class (2B) get a cold snack with a soft drink, others (2P, 2C) can buy snacks from the trolley or visit a dining car. Also, there are some seats at the bistro car (2E) which include any meals from the menu for the exact amount.
