My favorite hot dog stand is my own kitchen. Sorry, I always make hot dogs at home, as it’s one of the easiest quick dinners possible. Casper’s hot dogs are my choice, because I want that natural casing snap, but John prefers Ball Parks.
From my hot dog stand you can see all of Downtown SF, plus the suspension span of the Bay Bridge, and much of the East Bay.
Still, I’m glad to read your suggestions!
