The Rabbit Hole Coffee Sultanahmet is a cafe in Sultanahmet, Istanbul that serves Turkish breakfast and coffee. The Turkish coffee has a different flavor profile from an Americano, and Turkish breakfast and croissants can also be ordered. Terrace seats are cool at 8 a.m., and between 11 a.m. and noon indoor seats run out, so outdoor seating is used instead. The Turkish breakfast portion is large, so even for a group it is better to order just one.
