A huge "special" pide, veg , mush, sausage and egg is 12 tl in Nefes Pide in Paspatour. Wine by the glass is also a good price unless you have more than 4 glasses. Then buy a bottle.
The two of us have one big pide, mixed salad and 4 (large) glasses of wine for less then 50 tl. This place is also open all year.
