This is a cosy little place somewhat off the beaten track. The food, atmosphere and service were all good. If you're in Kazan I'd recommend giving it a try.
It does sell fish however, at least it did when I was there in February, so it's not completely vegetarian. And as sometimes is the case in restaurants in Russia, it didn't have available a lot of the items listed on the menu.Pros: A veggie friendly place in Kazan, atmosphere
Cons: Not everything available, sells fish
