I like to say "Fez" - saying the name makes me feel hip.
I've been a few times (lunch, happy hour, dinner) and the mix of clientel is interesting. Are you 60 or older. Go on! Are you 21 ? Solid! In your mid-30s on a date? Right on! This place is open to it all and you won't feel uncomfortable.
Let me start with the drink because it is what I love best about FEZ. Try their Dark Chocolate Martini! (If you read my profile on Facebook, my favorite past-time is taste-testing Chocolate Martini's).
Try their sweet potato french fries with the garlicy (I think) dipping sauce!!!!! And interestingly, Sweet Potato french fries DO NOT clash with Chocolate Martinis.
The food wasn't that impressive. I've tried a couple of dishes and remain satisfied, but not wowed.
My two cents: I think Switch (same owner) serves tastier fare. But, man, those Dark CHocolate Martinis will knock your socks off (maybe literally because they are pretty big.)
