Advantage of the place is that it is 100% vegetarian. The matter is that there is a high risk of opisthorchiasis invasion in this region if you eat in restaurants where fish is served, even if you eat only vegan food there. So this place is a kind of guaranteed parasites free oasis in Omsk.
There are some drawbacks:
Most of the dishes are not vegan.
Some food is pretty fatty.
It is self-service restaurant. That means if you come in the evening you get food that was cooked hours before - not very fresh and usually microwave oven heated or cold.
But service is is getting better gradually. And food quality also. In Govinda we trust. :)
