The best underground shows you will find will have free pbr and models as far as the eye can see. They are rarely announced, so keep your eyes out for promising openings, especially with Milk Underground coming up.
Death & Co is my favorite place for delicious cocktails and small bites. Their truffle mac and cheese and lobster rolls are delicious and love just about every drink on their whisky menu.
Designed by Frederick Law Olmstead (of Central Park), Prospect Park is where I go running in better weather and find an endless supply of flotsam and jetsam for casting in projects all year round. Thickets of trees, hidden paths, and rolling hills are an endless source of inspiration.
My favorite place on Bedford Avenue, this bookstore has both new and used titles. If you're patient and look close enough, you can usually find a book that's worth more than they're asking. Not to mention their stellar selection of magazine titles. Good for design, art, photography, sociology, fiction, and everything in between.
