Late chef Anthony Bourdain loved New York-style hot dogs with mustard and sauerkraut from Gray's Papaya. However, he stated that NYC hot dogs are not the best in the world.
For that title, he credits Chicago. As reported by Eater Chicago, Bourdain called a traditional Chicago dog "the finest hot dog on the planet. There, I said it, and I meant it."
A Chicago-style hot dog is an all-beef frank in a poppy seed bun with mustard, sweet relish, chopped onion, tomato, a dill pickle spear, pickled sport peppers, and celery salt.
Across his various TV shows, Bourdain enjoyed Chicago-style dogs at the lauded but now-closed Hot Doug's Sausage Superstore and sampled franks at Jimmy's Red Hots.
In an episode of "No Reservations," Bourdain stated, "I love few things more than meat in tube form and especially in, like, local, mutant forms of hot dogs."
