I was invited to Kiev for a banquet on a Sunday afternoon, and was pleasantly surprised. The food was top notch, which, when it comes to Russian cuisine, means that it was not hopelessly over salted or oozing with grease. I actually quite enjoyed most of the dishes I tried.
The decor is horrendous with the banquet hall chair covers pompously hanging over beat up chairs, and equally pompous synthetic linen. The service is like it was in the 80s in Russia: insincere and clueless. I was quite happy that there was no music -- I could actually enjoy a conversation.
I'd return there for the food.
