The Twin Cities has a long, proud history with the Jucy Lucy, a glorious burger, served at several rival businesses around town, that is stuffed with molten lava-style cheese. In recent years, the burgers have hit a new level of popularity, thanks in part to Blue Door’s creative “Blucy” menu, which goes well beyond the original American cheese and fried onion options. Saturday celebrates the 10-year anniversary of the first Blucy, and Blue Door is celebrating with an all-day party stuffed with fun at its University of Minnesota location. There will be live music from the likes of Purple Funk Metropolis, rockers Porch Knights, psych rockers General B and the Wiz, and DJ DeadMusik, among others. Beyond the Blucys, there will also be wing and beer specials, plus a special blueberry honey IPA by Indeed on tap. Giveaways and other fun more festivities round out the event.
