The Phoenix Landing really depends on what time you get there. It could be a subdued local pub trivia night, a fan packed sports bar, or even a full on dance party.

This is also a middle-eastern tapas joint, which serves pretty good food at reasonable prices.
This legendary Cambridge institution consists of an art gallery, 4 live music venues, 4 full bars, and no less than 3 dining areas (including the upscale Zuzu, below). Sample a large variety of Lebanese dishes served in a vibrant, artsy setting. The "Corner" dining area (enter at 480) features live music every night, often free, with belly dancing on Su and W. Extensive vegetarian menu.
They have 2 games: The Heist (you get to steal a diamond) and The UBoat (WWII submarine themed).
Has a huge collection of holography, rotating exhibits, and showcases some of the best "hacks" performed by students. Hacks at MIT are practical physical jokes taking place around the institute. For example: installing a somewhat functioning police car (complete with instructions for how to remove it) atop the great dome. This museum is great for kids and many exhibits are hands-on, including moving sculptures and a shadow room.
A Cambridge staple since the early days of the American folk music revival. Small, old-school feel with live music 7 nights a week, focusing heavily on American roots music. The Cantab hosts a folk music open mic on Monday nights and jams other nights, as well as small- to medium-sized acts every night. A must for those interested in the Boston folk music scene.
