I’ll do mustard, onion, & a little relish. Chili dog is O.K., but kind of messy. But, if you put ketchup on your hot dog & you’re over 11 years old - go F#CK yourself……
Michigans are good too. I used to work with a guy from Flint. They make their meat sauce and bread a little different than the Detroit-style Coney dog. A Detroit hot dog place is opening up near me soon.
