Stepping inside the Lexington Candy Shop on New York City’s Upper East Side really is like stepping back in time. There are the spinning stools of diners past, ice-cream sodas, frosted malts, Formica, and a general wear and patina on everything around you — no wonder, this luncheonette has been doing its thing since 1925. And it still makes your Coke the old-fashioned way: a shot of syrup and a seltzer spritz. There may be a time and a place for a defense of the "diner burger," but this isn’t it. Why? There’s a special burger genre to sample here: the Lexington Butter Burger. It’s far from the only burger place serving this rendition; Milwaukee’s Solly’s Grille (founded 1936) gets a lot of that love, but it’s ridiculously delicious nonetheless, and the panel ranked this rendition higher than Solly's (#33). Conventional burger bun, a flat, but juicy patty that has that caramelized brown crust, and a heaping, honking tablespoon of buttah that arrives still intact but melting. Salty and juicy, dripping wet and indulgent, you’ll appreciate the vinegary pickle to cut through it all, but the Lexington Candy Shop’s butter burger is a decades-old next-level move that always feels revolutionary.
