On the main hotel and restaurant street of old Istanbul, just off Akbiyik Caddesi, at Mimar Mehmet Aga Caddesi 16 there is a narrow spot with no touts outside, Sofa Cafe. And no surprise, inside I found an excellent restaurant with casual and relaxed waiters serving Italian and Turkish dishes. The place oozes of laid-back young people atmosphere. This is an oasis in an otherwise most touristy street of the city. I was lucky to stay in an excellent hotel almost next door. Would have visited more often if I had found this gem a little earlier on my week in Istanbul. A top spot.
