Not sure if sour beers sit right with you? Cascade’s minimalist roll-top garage space, which spills out onto Belmont in the summer, might change your mind. And with 16 rotating taps, sandwiches (pulled pork to fig-pesto-chevre) Cascade’s cozy patch of umbrellas and green picnic tables provides a snug place to expand your beer horizons—or stick to your favorite styles.
