I love classic Chicago food at Portillo's!
I went to the one in Tempe for the first time. I was very happy that it was such a great place to take kids, as there were three under that were 8 and under in our party. It's casual and it is very comfortable to take a large group (we had a large group, too).
It is a little overwhelming and busy going in there - just so much stuff and seeming chaos going on when it's so busy. But, the menu is simple and it was great eats. I love the hotdog with poppy seed bun with everything on it. Nothing like it! The onion rings were crisp and delicious, too.
Everyone in my dining party was very, very happy. Even the kids were happy with their food. I highly recommend Portillo's. Just remember that it is classic food from Chicago and not necessarily what you'd expect at a hotdog stand in the Phoenix area.
