I don't know how to start this, but, this place is magical! I've been to Istanbul with two of my dear friends, and in five days we've been here three times! The restaurant it's not a 100% vegan unfortunately, but it has a lot of vegan options and also local dishes like Muttebel, Sarma and so on!
During our tip in Istanbul we found a lovely bistro that I highly recommend. There are a lot vegan option on the menu and they have the vegetarian and vegan logo next to the dishes. This one is a mix of three appetisers: hummus, Turkish tabbouleh (kısır) and stuffed wine leaves. Everything was AMAZING, you need to try yourself
