If you want to go there, don’t mention that you have a Groupon if you have one. They will find excuses not to accept it. Be aware. The restaurant representative Yuriy was very kind and pleasent until I said I have a groupon, right after Yuriy said that he doesn’t have enough vegetables, just got a group of 20 people and won’t be able to serve us. I don’t think that I want to go there ever.
