Crab, shrimp, cucumber, ginger, wasabi
lots of things I've never tried in this thread. Sauerkraut is probably my favorite. Kimchi sounds really good, will try
Usually either relish & onions or spicy mustard, depending on what I'm in the mood for. I usually put sauerkraut on kielbasa, but I've never really thought to put it on a regular hot dog before. Maybe I'll try that at some point.
I'll usually have a Chicago style dog without tomato, or, mustard, bbq sauce, and relish
I have a "Chicago dog" every time I end up in O'hare airport for a layover. Very tasty, the pickled pepper on it is a really good topping.
God rest your soul
Hah, layovers suck but to be honest I'm always so tired that they all suck more or less equally, regardless of what airport I end up at. I'm just happy I'm able to travel to see family and such.
Crispy fried onions are the best.
If you have ever been to a convention or concert or other big event, and seen those street vendors out front with the grill carts grilling hot dogs, buy one. They are the absolute best and I always get one when I have the chance, even though they are usually a bit overpriced.
Here in California they are always wrapped in a strip of bacon, and usually the vendor will add ketchup, mustard, mayo, grilled onions, and a piece of jalapeno if you ask for it. It may just be a California thing, I'm not sure. They taste amazing fresh off the cart and usually cost $6 or $7. If it's a big event, the venue will be swarming with grill carts.
