coming down from nyc for the phillies-mets game tomorrow (don't worry, i'm a born and bred phillies fan--can't say the same for my son, though) and was wondering what the best food options are at the ballpark. is there a decent cheesesteak to be found? anything else worth noting and that won't take a second mortgage to afford? any good hoagies nearby that i might buy and bring in with me? help.
