Was in a popular restaurant the other night and had a bottle of wine, then due to unforseen circumstances ordered 4 more glasses of wine.
The 4 glasses of wine was 8 tl more than the bottle and that was Kavak.
Just check it.
Nefes Pide and Melodi give a good measure for the cost.
Last time I was in UK, 3 or 4 years ago I remember paying 6 pounds for a normal glass of wine or is my memory going. I also think I recently read a report on the airport cost as well.
