Food is really good but I found it kind of expensive. Around $13-$15 for a cheeseburger combo meal.
Really good crinkle fries and better ambience than White Castle for a sit down experience.
The main benefit right now is the White Castle is still an hour wait (even at 8 pm) to order food either through physical line or drive through, so the Portilllo's is alot faster. (maybe 5 mintues to order and then 15-20 total to order and get food)
