This is my go-to spot in Philadelphia. Only one other place downtown really compared and it shut down years ago.
The quality here is usually the best but perhaps not wholly consistent. But it's always come in clutch for me just when I need it to.
Sauce and crunch are both good but not quite elite. Best in the area for sure though.
And the atmosphere is the best place to just chill. Nice community spot used by the little league/kids soccer crowd but they're not usually a bother. I don't walk 30 minutes for nothing!
