Premise: The Lever Burger is a masterfully constructed, classic American burger. No foie gras, no truffles, no duck fat: just beef, orthodox toppings, and a grilled white bun. The Juicy Lucy takes its cue from a regional specialty in Minneapolis in which cheese is embedded inside the burger, so as to ooze out upon biting. Advantage: None.
Burger: Both burgers are made from meat mogul Pat LaFriedas ground beef, the gold standard, but Sheridan Squares mix includes some short rib, which gives it an added depth of flavor missing from Levers chuck-and-brisket mix. Advantage: Sheridan Square.
Bun and Toppings: The Lever Burger comes on a grilled Portuguese roll that more than holds up its load. The Juicy Lucy is served on a comparatively fluffy brioche bun that submissively disintegrates as you eat. The Lever burger has oven-roasted tomatoes, house-cured pickles, and intense, wine-and-balsamic-stewed onions. The Juicy Lucy has straight-up grilled red onions and bacon. Advantage: Lever House
Verdict: Lever House's is more composed and masterful, a burger for the ages. But for a visceral, messy, primordially gratifying burger experience, the Juicy Lucy delivers the goods. New York is big enough for both of these, the Carnegie Hall and the Bowery Ballroom of burgers.
