Dumbo can no longer be labeled “up-and-coming” — it is up and it has come. Narrow cobblestone streets and warehouse spaces offer a raw, industrial appeal. And while designer boutiques and trendy restaurants and bars are everywhere, don’t expect a raucous late-night scene. Dumbo caters to those who seek a Tribeca vibe, but want a little distance from the hustle of Downtown Manhattan. It’s no surprise that it’s now known as a place where established local artists, musicians, and creative types can rub elbows with A-list celebrities.
