I don't know! Sorry, all I ever got was a pizza steak with provolone. I was afraid to order anything else because I didn't want to not like it.
Here's their menu. It looks like the only cheese choices are Whiz, American, or Provolone.
You are welcome to ask for Swiss or Muenster, but you might find yourself being frog marched out the back door and kicked into the middle of 4th Street.
Go there on a Friday night and check out the enormous mound of rib eye that's cooking on the griddle. It looks like Mt. Hood in Oregon.
Well, they have a small mountain of steak in this Dalessandro's video, but it is a tasty mountain!
