Nathan's is kind of a chain, but you won't find hotdogs at places like McDonald's and Burger King, or most places with Drive Thrus. Sonic does have a number of different hotdogs, as does Johnny Rockets, though both of those are tougher places to track down in my neck of the woods. Hotdogs tend to be made by the toppings put on them in that case, which is mostly a waste because aside from chili, cheese, and/or mustard toppings on hotdogs are gross. Some specialty places are better as they are more likely to use different kinds of meat to make the hotdogs.
