I'm not much of a hot dog guy, but I do like the ones they have at Five Guys. I prefer their burgers, but once in a blue moon I'll grab a hot dog from them.
All I have ever gotten on hot dogs in my life is ketchup.
I'm a very odd duck about certain foods I won't touch, I seem to avoid any sort of white sauce or creamy shit like the plague. It unnerves me for some reason.
I won't touch:
Cheese (except on pizza)
Alfredo
Mayonnaise
Sour cream
Cream cheese
Cottage cheese
Miracle whip
Eggs
Mustard
My burgers I just get with ketchup, bacon, and mushrooms. I like grilled onions and regular onions too, but then the burger gets busier than I like. So I just keep it simple.
Pickles can be okay on their own once in a great while, but I detest what they do to the flavor of anything they're added to. It ruins a burger for me. Too strong.
Oddly enough I love milk and of course ice cream... so the thing with cheese and white shit is definitely not some lactose-pussy thing, or anything like that. I just find white sauces gross. Always have.
Brown, red, and black sauces are where it's at... BBQ, ketchup, soy, teriyaki - now we're talking.
