not to mention the tempting house-infused Horseradish vodka
...which is quite good. They also occasionally have homemade pepper vodka and herb "hunter" vodka (
okhotnichya)*. I don't think the food is at all inauthentic; it just represents a kind of high Western, urban teahouse style popular in Moscow and Petersburg which has filtered through to America. The U of C Russian Choir (
www.golosa.org ) has long been friends with RTT even though we're in the Siberian Christian tradition and the owners are in the southern Jewish tradition; there is considerable difference in cuisine, language, and music, but the differences are familiar and embraced both there and here.
A very good deal is to walk in right as they open on a weekday or just before or after lunchtime on a weekend and just get a plate of dumplings and tea service - they'll bring you the carrot salad and pickles as well, along with citrus, jam, house-made sour cream, and bread, and you can have a feast fit for a tsar for $11.
*The best flavor of Stolichnaya for me and many others is/was the Okhotnichya with herbs and honey. They sadly don't distribute in the States anymore. If anyone has run across a dusty stash somewhere, please let me know; I'm out of my stockpile from my last Russian trip in 2005.
