La Goulue
For excellent people-watching while you sip your French 75, you can't go wrong at La Goulue. The old school Upper East Side mainstay is as stylish as they come, frequented by New York socialites (including plenty of Real Housewives). Whether you snag an al fresco table on the sidewalk or tuck into an elegant, candlelit dinner inside a leather banquette, you'll find yourself instantly transported.
La Goulue, 29 E 61st St.
