*sigh*  I really wanted to love this, but it was just ok.  After reading all the positive yelps and testimonials on Pop's website, I was expecting a fun and delicious experience.  I imagined myself giving my order to a gruff but charming grill master, who would ask me 'wit' onions? in an authentic Philly accent.  What I really got was a grill master who was just gruff and apparently couldn't hear my order, because when I got my cheese steak home, there were no onions on it at all!   \n\nOk, the cheese steak itself:  the meat was not fatty or greasy, but slightly bland.  I enjoyed the cheese whiz and the bread was very good.  I think if they had included the onions, things would have been tastier.  Also, in the hours since eating the steak, I have been a bit 'indisposed', but this in and of itself has never been an index of whether I would return to a place if the food tastes good.  (masochist!)\n\nSo all in all, I think I would try it again probably.  But I'll also try their competition in town and yelp the results.  :)
