Mamalyga

Just a stones throw from Nevsky, this restaurant offers you an assortment of food from the Caucasus region, including Georgian, Imeretian, Armenian, Adzharian, Megrelian, and the cuisine of Swaneti and Guria. Authenticity is a word that the owners use quite often to describe their food and it comes through in the food that is prepared by local (to the region) cooks. The menu features a mix of well-spiced (the food is not watered down for local consumption) shashliks, salads, khachapuri, and pretty much anything else you could want from the South Caucasus.
Also at Belinskogo ul. 5 (open 08:00 - 01:00, metro Nevsky pr.) and Leninsky pr. 84/1 (open 12:00 - 01:00, metro Leninsky pr.).
