Eclectic doesn't even begin to describe the levels-nay, stratospheres-of communities that overlap in this tiny-but-tenacious patch of the city. Ground zero for live music starts at the intersection of Mass. Ave. and Brookline St. (you can't miss the lines every night), and the sound bleeds outward from there. Precisely brewed caffeine, Prohibition-inspired cocktails, and high-octane smoothies are always near at hand. Clusters of historic churches commingle with startup video game offices and brightly lit Indian restaurants. If you pass by at he right time, you can catch a whiff of something sweet - the area's candy-making history lives on with a bustling Junior Mints facility.
