I didn't think Nathan's was anything special. Most hot dogs taste pretty much the same to me, though.
There is a place, though, down the street that sells steamed hot dogs for 69 cents a piece, that's good for a snack. It's a chain, Billy K's, but I'm not sure how big it is, I've only ever seen one more of them. You get a ton of fries with their combos, but their drinks are tiny.
