A beautiful place on a pedestrian street in Istanbul. It's a lot more interesting inside than outside. You can admire the decorations in the cool. It also has many shops and eateries.
Pleasant atmosphere. There are many small restaurants. The cuisine is traditional Turkish. Musicians walk between the tables, perform songs and play musical instruments. Of course, it's not free (they don't require any money). The visitors themselves give the musicians as much as they see fit.
