Jucy Lucy's are famous. And if you're from the metro area and you haven't had them from both Matt's Bar and the 5-8 Club I hope you've been living under a rock for the entirety of your adult life. It's an amazing burger, and I would say that sampling Jucy Lucys around the cities it a good use of one's time.
Not only is the Jucy Lucy a good burger, it's a food that has put Minneapolis dining on the map. America's Test Kitchen has picked up on its popularity, testing the recipe enough to come up with a well-tested recipe sure to make your backyard BBQ an event to be celebrated. The Travel Channel's Food Wars and Man v. Food have been to Minneapolis to test the burgers. If national television shows are coming here to test the epic burger, shouldn't you get out there and do the same?
I also think that it's only fair to mention that there are also some great versions of the Jucy Lucy in St. Paul. The Nook was one of our favorite burger places when we lived in St. Paul, they serve the "Juicy Nookie Burger" which is their version of the Jucy Lucy. The Blue Door Pub also serves cheese stuffed burgers, their flagship burger is the "Juicy Blucy."
I like a Jucy Lucy just about anywhere, as long as the cheese has cooled down enough that it doesn't burn my tongue off. But, I'll throw my two-cents in and say that I Matt's Bar's Jucy Lucy is my favorite. My preference for Matt's Bar is based primarily on the ambiance - the menu is posted on one wall and it's a cash only kind of place where it really is about the burger.
If you haven't tried all of these Jucy Lucys, get out there!
