Mandabatmaz ★ 4.6
Mandabatmaz in Olivya Geçidi, a one-table Beyoğlu Turkish coffee bar running since 1967, the cup of foam so dense the buffalo doesn't sink. Family-friendly.
Why locals love it: Tucked inside the Olivya Passage off Istiklal, easy to miss for anyone not looking for the unmarked alley.
Tip: Order an orta-şekerli (medium-sweet) and stay for two; the kahveci will keep refilling water.
