I think the cheese that's in the Juicy Luicy at The Anthem is Velveeta. Even so, I've had it a few times and it's a solid burger if your on a Division street bar crawl.
There's also a tasty stuffed cheese burger that goes by the name "The Ooey Gooey" at Phil's Last Stand in Ukrainian Village. It's a char grilled burger stuffed with Merkts Chedder, topped with grilled onions and "fatso sauce" (think In and Out sauce clone.) They also serve up fresh hand cut, twice fried fries. It's really quite good. Also, they have a nice little "secret" menu. For example, you can have em cut your spuds shoe-string style. It's not on the menu but just ask and they won't look at you weird. You can also have a fried egg on anything, just ask. I think the next time I'm there, and Phil is hanging around, I'm going to try and ask him to make my burger "animal style" and see what happens.
After all, their regular "Fatso Burger" basically aims to be a char grilled "In and Out Burger" clone. Anyhow, I can't sing enough praises about this place.
Then theres Lockdown Bar and Grill around the corner on Western, also in Ukrainian Village. I'll give you their websites description of their "Lockdown Warden Burger;"
Certified Angus Beef® infused with Bacon,Leeks,Garlic and Shallots,stuffed with Merkts Cheddar, topped with Fried Leeks and Shallots with Truffle Oil. This is a mighty fine stuffed burger. Tuesdays is half off burgers, tho fair warning; the Warden Burger is exempt from the special.
I believe Phil, of Phil's Last Stand, is the father of the owner of Lockdown.
I guess UK Village is the place to be for a stuffed burger in Chicago eh?
