First was Dyer's Hamburgers in Memphis, TN where the burgers are made in 90-year old grease! Yep...you read that right! (Note to HixsontoLeVias: go check it out and give us a report!)
Next was Ted's Hamburgers in Connecticut (sorry, I missed the name of the town) where they make steamed hamburgers.
Then it was on to Sadalia, MO and The Wheel-In Drive-In, home of the Peanut Burger Burger. Yep...they slap a dollop of peanut butter on that patty while it's cooking.

Next stop was Solly's near Green Bay, Wisconsin where they make Butter Burgers. A huge helping of Wisconsin butter is laid on top of the patty while it's cooking. Interestingly enough, the eatery recently relocated and it's now just a few doors down from the Wisconsin Heart Hospital!
Then on to Meer's, OK and The Meers Store where they make Texas longhorn beef burgers! (Note to self: have to go eat here sometime soon!)
Next stop: Bobcat Bite in Santa Fe, NM where they make green chile cheeseburgers!
Followed by Louis Lunch where they make hamburgers in broilers that have been in use since 1898! (Sorry...didn't catch the name of the town/state where it's located)
And finally, for all of you Chicago Cubs fans...The Billy Goat Inn & Tavern in Chicago, IL in the shadow of Wrigley Field. This eatery was the basis for the infamous Saturday Night Live "Cheeseborger! Cheeseborger!
Cheeseborger!" skit. Many of the SNL alumni who were originally from Chicago frequented this establishment.
