Went here once during my stay in Irkutsk, and found it easily using the address provided in another review. The place has a good vibe, and the staff were nice enough.
There was quite a variety of food to choose from, but unfortunately not many vegan options, and no vegan desserts. I had a cabbage and dill soup, roast potatoes, little potato balls and what I think was a nut meat patty, all of which was delicious. The other vegan foods available were rice and buckwheat. Make sure you ask the staff which dishes are vegan, as we thought some of the curries looked great but they all contained cheese.
Cons: Weird payment system , Not many vegan options
