It's a great place. The food, service, and interior design are simply beyond praise.
I tried the misso soup here, just wow. The staff is competent and knows their business. What is not a little important, if you do not know English or do not know English well, the staff knows and will answer you in Russian.
Also, the waiting time for the order is short. I will definitely visit this place again when I am in Tbilisi. I would give this place a 7 out of 5
