In the burger business, some fight passionately for the right to embellish between the buns. And then there are those who choose not to mess with a good thing, those who believe in the standard architecture of one of America’s proudest foodstuffs. If your ideal burger fits the latter description, look no further than suburban Edina’s classic throwback diner, Convention Grill, which dates back to 1934. No frills. No monkey business. Aided only by a colossal stack of skin-on fries that, alone, are worth a visit. And what are a cheeseburger and fries without a thick, delicious malt or a cherry and vanilla Coke? The retro décor, complete with a jukebox in the corner and yellow-and-red plastic squeeze bottles on each table, will remind you of a simpler time, or of Nick at Nite at the very least. No alcohol available. Serving lunch and dinner daily.
