The Tuesday night open mic at the M Bar is good for a few laughs, providing a wide variety of local comics struggling for visibility. The $5 cover is waived if you make reservations for dinner. With standard pasta fare and main courses between $10 and $20, it might be worthwhile if the dishes weren't so ho-hum. Fortunately, the entertainment more than makes up for it. I suggest ponying up the $5 bucks and having dinner beforehand at the Cuban restaurant next door, Floridita.
