You must taste it! One of the best ice cream shop in Istanbul / Sisli. This cozy & old fashioned shop have various flavours like lemon, cherry, mastic, pistachio etc and if you want chocolate sauce & coconut/hazelnut powder on it IT IS FREE! They made their ice cream from real milk and only natural ingredients. I tried cherry, lemon, milky and all of them are delicious. Please note that you can make a mixed scoop, just ask for it!
In winter you can also taste sahlep (is a flour made from the tubers of the orchid genus Orchis) and boza (a winter drink made from millet semolina, water and sugar) which is traditional drink in Türkiye.
