For a second I thought it was a debate between the two cities. My initial though was 'Which is better? Its like comparing Herpies and AIDS to see which you'd rather have.' Then I saw the food part and all was fine. I have to say a good philly cheesesteak will really hit the spot when you're hungry. But Chicago pizza has so much more diversity. Come home drunk and whats the food you crave? Pizza. Have a bunch of people over for a party or to watch the game? Order Pizza, so in Philly's defense. They have a solo food whereas Chicago feeds a few.
