Am I going to get sick from eating a Chicago hotdog?

My bf is a meat-eater and he says that I should make an exception to my vegetarian diet to try an authentic Chicago hotdog. They are Vienna hotdogs, cuber relish, mustard, tomato, onion, celery salt from this place called Byrons. We are going to Chitown next week and I'm petrified of actually doing it, but I sort of do want to experience the taste just once before I die. The only hotdogs I've ever eaten are the cheap store brands here in Florida. He says there's absolutely no comparison. Should I do it or will my body reject the meat? I haven't eaten seafood, poultry, pork, venison, beef (no animal protein) since I was 17. I'm 24 now.
