Breakfast is provided in your hostel. Most lunches and dinners are taken in university restaurants, so called “Mensa”s; see the schedule for precise information. At each lunch or dinner in a Mensa, you may take a main course, two side dishes (like potatoes, noodles, vegetables), either salad or dessert, plus a soft drink. Show your badge at the cashier for identification; no badge, no food.

During BOI, the Institute of Computer Science provides Internet access to all partcipants.
