Once we found this place (towards the end of my stay in Istanbul), it became one of my favorite…read morecafes in the area. The coffee is good (they have an espresso machine, so you're not stuck with instant coffee), the cakes are gorgeous, and the staff was so friendly.
I had the same fruity cake twice since I'm not a fan of chocolate. It was light and fluffy both times and big enough to share. When we asked for brown sugar, someone went on the hunt for it and returned triumphantly with it a few minutes later. There's not much English spoken here (for any other tourist types), but the employees know enough to easily get the gist of things. There's also a married couple that works here who are awesome! They're a funny pair for sure.
