From walking your dog in Carl Schurz Park to picking up medical knowledge by osmosis, Yorkville on the Upper East Side has a lot going for it. What it doesn’t have, however, is a lot of restaurant options in the date night department. Enter Chez Nick, an American bistro where you can get a glass of wine and ricotta toast with someone who thinks your “two truths and a lie” are clever, or cucumber martinis and lemongrass pork steak over garlic fried rice with someone who knows your social security number. There’s no seating at L-shaped bar in the middle of the dining room for the time being, but the small wooden tables near the big windows, or the slightly elevated alcove in the back, or the quiet sidewalk outside are all good places to share duck ragout-drenched pappardelle.
