Lizard Lounge

A short walk from Harvard Square, this diminutive basement bar puts on a jam-packed program of shows. The beauty of the Lizard Lounge is that there is no stage. Instead, bands perform on a well-worn rug—the only delineation between audience and performer. The musical fare runs the gamut from rock and folk to Americana, along with the odd Boston Opera Underground performance. There's great food too, served in the Lounge early on, and all night up in the Cambridge Common restaurant.
