Bacon, sauteed onions and mushrooms, bbq sauce.
I recently had a "Rochester Original Hamburger" at The Distillery (Rochester NY local chain of 3 restaurants) in Greece, NY. It is listed on their menu as an 8 oz burger with mustard, onions and meaty hot sauce. I got it with onions, sauteed mushrooms and the meaty hot sauce (no mustard).
The hot sauce had an interesting taste. It reminded me of cloves and/or cinnamon. There was a little bit of heat, but not too much so that you couldn’t taste the other ingredients. My Rochester-based eating companion said that hot sauce was a Rochester staple. I tried to convince him to go to Nick Tahou’s so I could try my first garbage plate, but he wasn’t up for it — maybe next time!
