When I decided to move back to New York, the first good decision I made was to join Serve. The second was to make Brooklyn my home.
Although I've lived in New York before, when I first moved back I kept making freshman errors, like jumping on the subway going in the wrong direction. If you do this on the F train you end up in Queens, not Brooklyn.
Not that there is anything wrong with Queens.
My friends have been quick to recommend various places they like in Brooklyn. Here are a few I've enjoyed during my first year:
Best for pizza
Friendly yoga place
A little culture
