Barney Greengrass
There's a reason that this list contains more than one restaurant that serves "Jewish" cuisine: whitefish, blintzes, and bagels are restorative dishes, and with a side of pickles and onions, just bracing enough to snap you out of your funk. Though the sturgeon sandwich at Barney Greengrass clocks in at just under $18, making it slightly ritzier than the average diner, it will fill you up for the rest of the day. The Upper West Side institution is consistently rated one of the city's best delis, and the Formica tables and yellow-tinged wallpaper show its dignified 103 years-old age.
Barney Greengrass, 541 Amsterdam Avenue (at 86th Street); 212-724-4707.
