For some reason, not every bar in town offers Sangria. Enter My Big Fat Greek. Sangria here is good and in fact, I got really drunk off some chocolate martinis there a few weeks ago too. Nearly forgot about that.
Aside from booze, My Big Fat Greek has great food IMO. I really like the chicken salad or the chicken pita. The hummus is also always a great starter.
I've always had attentive service and like the general Greek vibe I get when I eat here. Casual atmosphere, great for lunch or for dinner. Good location in Old Town next to many shops and bars. Highly recommended!
