I had the displeasure of having to have a taste of Lutefisk. I can only describe as Fish Gelatin.
New York and Chicago are known for their hot dogs too.
California — Roberto’s #99 Carna Asada Burrito.
IMHO, the best hot dogs in North America come from street vendors in Toronto. Your choice of several different buns, many different dogs and sausages, every possible condiment, and you can pay with loonies.
