It's not just a cafe, it's a flower shop. You can find and buy any type of flowers and plants there, and then celebrate it with a glass of wine. Cuisine is international there, but you can find some Georgian basics too.
Nice dinner in a huge outdoors flower shop (just imagine how good should be smell there!), with the view over Narikala, Rike park and dancing fountains, and TV tower in front of you. Isn't it a perfect idea for a great evening?
Try to book a table with a better view in advance: they are almost always taken.
