"Underdogs in Philadelphia, PA"
You've got to go check out Underdogs in Phildelphia! It's a little joint right in the middle of the financial district of the city that makes amazing hot dogs and will even give you a vegan dog if that's your thing! They do monthly specials, one of which was a PB&J dog that was insanely good. And the aoilis they serve with the fries are ridiculous. https://www.grubhub.com/philly/underdogs/?showSmallSearchWidget=Y
