Half is a club, and half is a restaurant. It is filled with the requisite "pretty people" but doesn't have a stuffy or uncomfortable atmosphere. They seated us right away on booth benches at knee height coffee tables.
Everything we had was good, but if you go, I highly recommend the humus and the lamb chops.
Oh, by the way, like any good Mediterranean restaurant, they had Guinness on tap.
