Unlike standard poodles, giant goldfish, or competitive bodybuilders, the large version of a small burger is scientifically more acceptable and less socially unnerving. Taste multisize meat coins and more with today's Groupon: for $6, you get your choice of a deluxe certified Angus beef burger, deluxe chicken burger, jumbo veggie burger, or three Kobe beef sliders at EJ's Luncheonette on Third Avenue on the Upper East Side (up to a $10.50 value).

Dishing out classic, American comfort fare in retro diner fashion, the upbeat servers at EJ's charm tables with classic sandwiches, salads, and breakfast plates. Build a burger via EJ's new menu of pattied palate pleasers. The 8-ounce certified Angus beef burger is a meat paperweight adorned with ringed red onions, pickles, lettuce, and slaw or french fries (a $10 value). Diners can appease bovine BFFs by opting for an 8-ounce freshly ground chicken patty (a $9.50 value) or a jumbo veggie burger, which, though smaller than a frisbee, comes slathered with guacamole and layers of tomatoes and sprouts (a $10 value).

Mock white-linen dinering unfolds with three Kobe beef sliders tucked neatly into potato rolls and topped with grilled onions, pickles, and EJ's secret sauce (a $10.50 value). An Upper East Side landmark, EJ's is so old school, it doesn't deal with futuristic credit cards, so make sure you’ve got enough cash for a tip on your journey back in time.
