I like ketchup. I won't apologize for it. I think it goes well on hotdogs... though not on a Chicago dog. But that has enough on it to forego the ketchup. The ketchup would throw off the balance.
But ketchup is sweet and sour and I have a particular like for sweet and sour foods. So the combination of ketchup, mustard, and very finely diced onions on a good hotdog is fantastic.
Or go another route with a nice bratwurst with sauerkraut and mustard... also excellent.
