(Taken from a guest comment on Qype) Wow! Cologne has needed a bar/restaurant like this for ages. I have been 3 times already. Sin is original for Cologne. Love the cool decor. Not pretentious. Great food with specials that change daily. (Trout tartare and Braised Ox Cheeks are a particular success) Good value too. Cute attentive staff. In Paris/London such dining experiences are not as hard to come by but generally cost infinitely more and the quality is at best average and the service generally crap. Not so in Cologne. Sin is 'in’. I’m hooked and a regular 'Sinner’.
