Maggie's Diner was built in Madrid, NM for the film, but the producers were asked to leave the building standing when filming was complete. It is now a gift shop that sells Wild Hog and Del Fuego souvenirs.
Although the guys are portrayed as being suburbanites-turned-bikers from Cincinnati, Ohio, none of the filming in the movie actually took place in Cincinnati.
The original script and logo line featured the notorious Hells Angels motorcycle gang, but it was later changed to the Del Fuegos after the famous club sued Disney.
As the Wild Hogs first enter Maggie's, Maggie is seated at the counter. However in the very next shot she is standing behind the counter with her back to them. In the same series of shots, she also turns her head to look at the Wild Hogs twice.
Doug Madsen: You know what's so stupid about this? We wanted to be like you guys.You know... because what I see here is just a bunch of grown men whose biggest decision in life is 'sleeveless or... uh... sleeveless? Do I shit behind the rock or over there by that bush?' Grown men... this is pathetic! You go ahead kick our ass, okay, because we are not the posers. You guys are the posers!
