Given the current prices in Istanbul, such locations are a great option. It was delicious to me. I took half a serving of meatballs with potatoes and eggplant and zadzik (yogurt sauce with cucumbers). Simple food, but very tasty. There is unlimited tea (I didn't take it).
The tables and floors are clean, the toilet is clean, but the ventilation is poor (it smelled bad).
There are a lot of people, someone eats quickly, I sat for a long time - I needed to recharge my phone.
The dining room is inexpensive and delicious.
Lunch for three came out 1125 liras: 2 soups, 3 meat dishes, 2 vegetable dishes, soda.
Bread and tea are free of charge. The staff is friendly, speaks minimal English.
