Portillos by Knotts
As a Chicago area native, now living in SoCal, I whole heartedly agree with this!! If we go down the night before or leave the parks early, we will usually stop at Portillos.
We always stop at Pizza Press across from the main gate. Great little place!
Wait wait wait wait wait. There's a Portillo's by Knott's??? (Asked the Chicagoan who'll be moving to LA in 2015.) Really???
