The American diner has been reimagined at Nickel & Diner, a spiffy art deco venue that’s a coffee shop by day and a fashionable hangout at night. Situated on the edge of Chinatown, the space was once a cheap Chinese buffet and has been utterly transformed with comfy booths and a long counter. At breakfast, get the classic egg sandwich with oozing yolks and hickory-smoked bacon. The grilled BLT and the burger with shoestring fries are standouts at lunch. The menu expands at night to include yellowfin tuna crudo, seared scallops with foie gras, and roasted chicken glazed with miso mustard.
