I'm expecting some pearl-clutchers to show up in the thread, but Bushwick is a great place for young people. Come summer time, the Morgan stop on the L is flooded, and there are a ton of bars and things to do in the neighborhood.
It has gentrified a billion percent in the last 15 years. I remember when Roberta's opened, and an employee ended their last shift topless. Now Roberta's has a location a block from MSG. Now the rent prices are probably insanely stupid for what Bushwick used to cost, but is ideal for anyone young.
