This story of a Dutchman being beat half to death by 360 restaurant staff is sadly only one of many such reports on one of Istanbul's most famous/infamous restaurants.
If physical violence isn't enough to keep me away, the uninspired food sure will. My last meal there was something close to what I'd expect from a dinner at the Holiday Inn. Some beef, some gravy, some overcooked vegetables.
The view is wonderful but there are plenty of kynd places to take that in.
