I will echo the sentiments of the previous reviewer when it comes to the location of the place - this is not an easy place to find, and we didn't realise it was connected to/part of a hotel. However, it is worth the effort!
With a vegan in tow, finding food that suited the two of us in Istanbul is a little tricky, but the menu for this restaurant sounded promising, and it turned out to be a very good match for what we wanted. From the excellent starter plates (covering stuffed calamari, delicious vegan dolma, a baked aubergine dish and a thick pate made from white beans) through to our mains (hers a bean/vegetable stew, mine an unusual but fantastic lamb dish with apricot, almonds, grapes, pistachio and onion) the foods was wonderful. Washed down with a local red wine - and yes, I was genuinely surprised by the quality of the wine - it was a truly lovely meal. We had no room for deserts, sadly, but they also sounded great. Along side a complementary tapenade appetiser and endlessly free mineral water and breads, this was a very, very good dining experience.
I'd love to have eaten here during the summer months as the views from the terrace looked to be a great backdrop to stare at while eating, but that didn't really take much away from our evening.
Certainly not the cheapest place in Istanbul, but worth it if you want to splash out on a superb evening of food and wine.
