Georgian restaurants in Moscow tend to be either expensive or tacky. This small family-run place is neither. Come with friends and order a selection of appetisers, such as pkhali and lobio (both made of walnut paste), khachapuri (Georgian cheese bread) and kharcho (rice with beef or lamb soup). Bless you if you can still accommodate a main course after all that!
A bottle of Kindzmarauli red wine might help to increase your consumption capacity.
