The restaurant is very conveniently located at the very center of Kaunas. The menu is also rather unique, with many "old school" dishes. Prices range from 3 to 5€ which is a good value because portions are not small.
The only negative thing is also mentioned in other comments: it's a health food restaurant rather than a place motivated by ethical vegetarianism or veganism. Some dishes look suspicious because it is not clear what ingredients exactly they use. When you ask, they say there are no butter, eggs, milk, etc., but they may be using margarine that has casein or vitamin D3 in it (there were several cases when such thing was found out). Nevertheless, some dishes are clearly vegan and there are quite many of them.
Cons: unclear ingredients
