I am not from Chicago, and I have never been or heard of Portillo's until my boyfriend told me about them. We made the ride out to Scottsdale because he was craving some crinkle cut cheese fries (which are fantastic!) He had a beef sandwich which looked phenomenal, and I totally messed up and ordered a grilled chicken sandwich. My sandwich was good, but a place called Portillo's Hot Dogs, and I get a chicken sandwich?? I can't wait to go back so I can try a hot dog, and do it right. However, I did get the cheese fries, only regret is that I didn't get a bigger size ;) Service is good, atmosphere is fun, and I love the 50's music they play! The restaurant is absolutely HUGE, and I can't wait to visit the new Tempe location.
