In PerÅŸembe Pazarı (near Karaköy), on the Golden Horn waterfront below Galata Tower, I sat every day with a beer. A shopkeeper told me it was OK to drink in public, and I saw locals doing the same. Still, when two policemen checked my papers, I thought that might be the problem, but no — probably I just looked suspicious, lol. The last time I was in Istanbul in 2013 , this part of town was different. The walking path didn't exist. Instead, all the seafood restaurants were right on the seafront; now they have been moved back from the water to the little street behind it. Back then, fishing boats docked here, and there was also a small fish market, rather than the cruise yachts you see today. Still, it is a nice little spot, and I returned every day to chill a bit.
