My husband has tried every hotdog on this menu and he can't pick on he didn't like. Gun to his head, he could live without the mustard one (wunderdog... But it's still soooo good!
Th veggie chili vegan dog is one of the best on the menu! The Colombian is also amazing due to the grilled pineapples! If you want to try a different flavor profile, try the Tokyo one. It has fried seaweed (I think fried) onions and wasabi mayo. Very unusually but delicious. The Vegas hotdog is Tofurky and grilled so it tastes so good.
If unsure what to order, ask the owner! Super nice and truly loves what he does!
