Pete’s Tavern

Bar in Union Square, Flatiron District & Gramercy

With its original 19th-century mirrors, pressed-tin ceiling and rosewood bar, this dark, atmospheric watering hole serving up brews since 1864 has all the earmarks of a New York classic. You can get a respectable prime-rib burger here and choose from 17 draft beers, joined by everyone from post-theater couples to the odd celebrity (see photos by the restrooms).
