Today, Labor Day, I went to the drive thru. I ordered an Italian sausage on a hot dog bun with mots and a side of beef gravy. I went home to eat it. It was the worse Italian sausage I have ever eaten. Well, I didn't eat it I took two bites and tossed it. It's apparent that the sausage was not cooked fresh. It appeared to have been cooked the night before and heated up when I ordered it. Actually I thought they may have taken it out of the trash and slapped it on a stale bun and served it to me. It was way over cooked, dry and cold, the hot dog bun was stale as well. I have ordered this meal several times in the past. I haven't been to Portillo's in a while because it has become expensive. I thought I would treat myself today. I was very disappointed in the Quilty of the food. I can't stress enough just how bad the sausage was. It clearly was not fresh, I'm convinced it was from the night before. If I had eaten in the restaurant I would have brought it to their attention, however since I was already at home, I wasn't going to go back. I understand these restaurants are trying to stay in business and make a profit. I know it is hard, but when I pay nearly 9 dollars for an Italian sausage, I do expect it to be made fresh, not from the night before. To Portillo's management, You have to do better, this was just unacceptable.

Love Portillos! Really good
food. Friendly service and fast, even during the lunch rush! Everything was perfect! I ordered my cheeseburger without onions and they got it right. Many places somehow get that wrong. The restaurant was clean as well as the bathrooms. They have an area with screens you can use to place your order right when you walk in. Otherwise you can just order at the registers. Whichever you prefer. They have many food options to choose from and great dessert choices. Always love the set up and atmosphere at Portillo's. Enjoy the flavor more than the Portillos a few minutes from my house ! Great job.

A couple months ago I wasnt very impressed with the service. It took forever to get food, and the quality wasnt as expected, but my drive through experience recently has been great! I got my food in a timely manner, the order takers outside were polite and confirmed my order, and the employee who handed me my food was professional and confirmed my order as well. My husband is a portillos manager in St. Charles and I eat at this location frequently. Very nice experience👍

Ordered a beef with extra sweet pepper and dipped in the drive through. When I got home the beef sandwich wasn't dipped and it had two pepper pieces. They charged me 2 bucks extra for the peppers and I didn't get them. Check all your orders closely, they don't seem to operate with the same quality they used to.
