Tarbell's is certainly not the first restaurant to elevate the burger to lofty, beasty, Herculean status, but while size is in the shoe of the beholder, Tarbell's double-decker burger — all six, maybe even seven inches of it — is, buns down, the best burger in the city. The freshly ground beef, loose and hand-formed into two impossibly thick patties, is judiciously salted and peppered, drooling with juices that blush scarlet, grilled to a perfect mid-rare and shoved between a soft, slightly sweet bun that's slathered with a secret sauce and platformed with lettuce, tomato slices and squares of American cheese that melt into the depths of your fluttering heart.
