Sushi is good, and live jazz is good, so by the transitive property, Mad Monkfish, which has both, is good too (we’re pretty sure that’s how the transitive property works, anyway, go ask John Nash to check our work). This Mass Ave sushi place is a great neighborhood spot that’s a lot of fun, even when there isn’t music (Sun-Wed, usually). The two dining rooms are almost always packed, the rolls that take their inspiration from fairy tales and are topped with strawberries and crispy noodles, and there’s a sidewalk patio.
