As a local and a tour guide I can recommend this place. I love to have dinner there as it's not expensive, it's in the center of Tbilisi and everything is delicious. The have both European and Georgian cuisine.
If you want to relax, have great food and at the same time be in the city center you should visit this place :) <3
Evenings are beautiful there.
