My mom used to talk up NYC hot dogs like they were some miracle of sausage making. Color me surprised when I got there and they all tasted like, well, hot dogs. I'm very skeptical of any city's claim to having the best 'hot dog' as it's one of the few meat inserts that tastes the same just about everywhere you go. Now, the toppings may very and there are some mild gradients in meat-to-water ratio but a hot dog is a hot dog is a hot dog.
Fight me.
