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.
