From the Beşiktaş–Üsküdar ferry terminal, go right if facing the Bosphorus. You will come to a row of cafés. The last one before the pier ends is Sehil.
The last in the row of cafés on the waterfront in Beşiktaş, slightly hidden to the left of the Üsküdar ferry stop – and the most appealing.
The menu is decent and features Turkish and Western fare. The desserts – especially the sütlaç (milk pudding) and ice cream – are particularly moreish.
