It's a very pleasant and atmospheric place. Delicious tea and coffee. Hookah is also very good. You can hide from the heat and relax after long walks around the city. At least once, but it's definitely worth a visit.
A good cafe, closer to the restaurant level. European breakfasts, it is convenient that they are on the menu, and not the standard story from Istanbul - a bunch of incomprehensible food for 1000 lira. The portions are large, very tasty omelets, I was really surprised. Good coffee. Breakfast is served on the patio.
