Kalina is a Ukrainian cuisine restaurant in Tbilisi (located on 18 Shalva Dadiani street). Last time I was here (2016), you could try varenyiki, dumplings and other Ukrainian goodies..
The place has a pretty decent retro style interior, seems this interior style is trendy for Tbilisi. The same interior you can find at Gardenia, Barberstan... this retro interior style is trendy all over the world, chandelier lamp shades, jars on shelves and so on.

Overall the interior is pretty fine (just boring, as have been seen a dozen of times already) let's speak about food - Since this place serves Ukrainian cuisine I opted for Herring in coat, dumplings in a pot with sour cream and vareniki.
Look at Herring in coat:
