I lurve the Mezz!
I discovered it about four years ago, on a friends birthday. Another friend of ours was DJing there, so we went to hear him.
The lovely part about the Mezz, besides its low prices is the fact that if you go there often enough, it becomes a place where everybody knows your name. There was apoint where the waiters had a special table for us.
And the music is lovely, Saturday night is rock night, which I love. Tuesday night is trance night, and Kabir, the DJ, always has some pretty good stuff.
In the middle it became a horribly crowded social type hangout, but now I believe its back to normal.
A good place to go for girls/guys night out.
