This is a shot in the dark, but my boyfriend went to this Russian restaurant in Manhattan that he said was amazing. The only problem is that he doesn't remember where it was and never knew the name. He said it didn't have a sign, and you walked downstairs to get into it. It was like it was someone's kitchen in their home. Does anyone happen to know of the restaurant I'm describing? If not... can anyone recommend a good Russian restaurant in the city?
