One of the best, oldest, most popular, and most known Turkish belly dancing & folk dances show in Istanbul, Kervansaray is located near Hilton hotel near Taksim square. They organize this show every night starting around 20:45, even though there are earlier starts for special requests. You can dine during the show or just have drinks, there are various packages. It’s a tourist place of course, mostly tour groups and foreigners go there because usually Turks don’t watch these kinds of shows unless there is a special occasion. In any case, their belly dancers are beautiful :) and very skilled. Folk dances from various regions of Turkey are also awesome. Do not raise your expectations for the meal but the show is very good. I can recommend this for any foreign visitor coming to Istanbul, for a fun night.
