My friend Nick is in Istanbul right now, eating his way through the list of restaurants he'd compiled before heading to Turkey. Here's one that I recommended to him. It's a tiny, unassuming and very casual fish place not far from the Galata Tower. Jay and I ate there the night we arrived in advance of our Black Sea cruise. The place is terrific. Mainly because they serve simple fish, unadorned by unnecessary sauces or other distractions. Just good fresh fish. We sat at the bar had several kinds, including hamsi (Black Sea anchovies) and grilled calamari. So good.
