I really enjoyed this restaurant. Been there 5 times already (good choice when you're visiting Open'er festival but not only).
Very fast (but healthy) thanks to good 'canteen system'. vast choices of both vegetarian&vegan food- Slow buger recommended 100%! Delicious fruit shakes. Very big portions.
Prices are okay too, if you're a student you will get 20% discount.
