I think a decent bun is imperative to a good hot dog.
Serve me a cheap-o bun, I’m not likely to return. Unless you’re a cart and you’re on my corner, and the next cart is 5 blocks away with the same crappy bun.
Then, I’ll probably give you my $3.50 for the meal -it’s cheap. But I’m still not happy and usually have to go to Wegman’s to get New England style rolls and have a couple Hoffmann coneys (white snappys).
