I dined at Rus-Uz this weekend with a group of 10. Four of us shared several dishes (3 appetizers and 3 entrees) and were not disappointed in any of them. The stroganoff is not the stroganoff you usually get at American restaurants, and is much better. We tried the plov just because it sounded interesting and again loved it. Portions are not overwhelming but definitely on the large side (a bit more than one can comfortably eat).
As of the time I'm writing this review they don't yet have their liquor license, but they're applying for it. They have plenty of non-alcoholic beverages -- I had the homemade apricot juice (with peach and cherries, I think) and it was delicious, not the sickeningly sweet juice you get at a lot of places.
Save room for dessert, if you can. The dessert portions are also not small but oh so worth it.
Our waiter was wonderful. He kept the water refilled before we asked for refills, and really knew the menu (he was able to tell us they were out of a couple things before he placed our order). He brought the food out in stages, partially because of the size of our group, but nobody was kept waiting more than a couple minutes.
I'll definitely be back for more.
