You’ve heard this one before: A classy cocktail bar opens on the Upper East Side, an oasis in fratland (indeed, you’ve heard it at this very address before—the space was formerly home to the “cocktail haven” JBird). But as much as Seamstress distinguishes itself in location, it stands out for its mastery of American classics; the menu offers 50 of them, from the Aviation to the Zombie, plus new creations. The textbook-style menu (learn about classic drinks through history while getting tipsy) makes sense when you consider head bartender Pam Wiznitzer was a master’s candidate in food studies at NYU while bartending at the Dead Rabbit. The space has a sultry feel—tabletop candles, red leather banquettes— that’s great for dates if you’d prefer that to cocktail history.
