I just wrote about the awesome hamburgers at Charlie's on A Hamburger Today - a roadside shack just outside of Philly that serves up super cheap delicious quasi-sliders - maybe 3 or 3.5 ounce fresh ground beef patties. They also make an awesome hot dog.
The dogs are split & grilled Dietz & Watson, dressed with the same microsopic shaved-ice onions that come on the burgers, and served on a toasted burger bun. Delicious.
