If you have never been to a Portillo's you are missing out. The food is outstanding. I highly recommend the Italian Sausage sandwich with a large cheese fry.

We were in the area and noticed this place seemed packed. We decided to stop for dinner and was very glad we did. Amazing food selection, something for everyone. I ordered the Italian beef and side of onion rings. The meat was very juicy and the onion rings were some of the best I ever had. I can see why... More

Their beef sandwhichs are the best! I like their fries as well. They keep the long lines moving with people taking orders outside. Really good food!

Easy heat up directions then served and everyone so enjoyed the predictably wonderful... More

This restaurant concept is crazy. My friend and I were pulled into a line before we even knew what was going on. The concept is nuts! I had a fish sandwich was good but it should have come with fries or something else. It was so noisy and hard to find a seat. I'm not sure if I'd go back... More

Consistent service and quality AT ALL locations. Portillo's has nailed the formula. These venues are not for foodies or vegans. However, when you have the urge to "be bad," you cannot beat Portillo's for a dog, a beef (lightly dipped with some sweet, mind you), a combo and/or fries. It is amazing how Portillo's maintains the service (very fast), quality... More

I have never had a better Italian beef anywhere. The beef is so tender, the spices that are used is very, very tasty, and the prices are very, very good.

I love Portillos hot dogs. Recently tried the jumbo and it didn't disappoint. I saw the ribs and they looked fantastic. The others in our party had the combo which is beef and italian sausage and they said it was really good. Someone else had the chopped salad and said they crave this salad all the time. We love the... More
