Yes, you are absolutely allowed to eat on Deutsche Bahn (DB) trains, and for many travelers, it is a central part of the German rail experience. On long-distance trains like the ICE (Intercity-Express) and IC (Intercity), there is usually a dedicated "Bordbistro" or "Bordrestaurant" carriage. In the restaurant, you can sit at real tables with ceramic plates and enjoy hot meals such as traditional German sausages, pasta, or seasonal soups, along with beer, wine, or coffee. In First Class, you don't even have to leave your seat; a steward will take your order and bring your food and drinks directly to your foldable tray table. If you prefer to save money, you are also perfectly welcome to bring your own food and drinks (including alcohol) from home or a station bakery to consume at your seat in both First and Second Class. The only general "etiquette" rules are to avoid foods with extremely strong odors that might disturb other passengers in the quiet zones and to ensure you dispose of your trash in the bins provided at the end of each carriage. On shorter regional trains (RB, RE, or S-Bahn), there is usually no catering service, but eating your own snacks is still permitted. DB has also recently focused on sustainability, offering more than 50% vegan or vegetarian options in their on-board bistros as of 2026.
