Very good food, very good service, just a few small quirks that didn't go over well but all-in-all I'm coming back :-D
Ended up finding this place via a group deal site where I bought a voucher for it.
There was a misunderstanding in the reservation where I asked to move our appointment from 7 P.M. to 8 P.M. for two people, where-as they misunderstood my change request to 8 people. We ended up working that out, so no big deal there.
I'm 3 quarters Russian, so all-in-all I know a fair amount of my Russian food. The pelmeni (my fav food) soup was very good, and the Red Square salad I must say was rather amazing, among the other things we had.
The server forgot to place my mashed potatoes in the end with the rest of the "to go" items after having confirmed with me that I wanted to take it with us, which is a shame as I barely got a chance to touch it :-(
One of the best parts of the experience was that the server noticed that my voucher was good for up to $100 before taxes, he told me that I should get the most out of my money and get more things as I had to pay for the taxes that weren't included anyways.
Like I mentioned initially in the review, I'm definitely returning as the service was very professional and the food was quite good as well.
