360 Istanbul is the place to see and be seen, on the top floor of the historical Misir Building.
The multi award winning 360 istanbul is set in a penthouse perched on a 19th century apartment building overlooking the old embassy row in Beyoglu. It commands a 360 breathe taking view of istanbul all the way up of St Antoine’s Church and across the Bosphorus strait to the Hagia Sophia and out to the Sea of Marmara.
I was at 360Istanbul last summer. One of the trendier spots we stopped by. Consider going early enough to catch a sunset.
