  Absolutely over hyped!!! We were super excited for a new restaurant to try and being next to the Costco we go too often, couldn't wait for it to open. Wow...huge disappointment! There were 5 of us and no one liked their food. We all had different items, and everybody was complaining. I got the beef n sausage sandwich, and it was ok at best but so, so messy. I must have used a million & six napkins. My son also went back with friends, and the experience was the same. They said food was Meh also. I have asked my wife several times if she wanted to go there and give it a second chance and she says NO WAY. The food was also on the pricey side for being MEH! So disappointed! The people that give this place a 5 star rating must not know good food or they are overwhelmed with nostalgia. What a waste of a great location too. I am pretty sure we will never go back.

  Absolutely disgusting. Service was terrible. Ordered 5 items on the kiosk and watched 15+ orders behind me all receive their order before ours. After waiting 20min, on a non busy monday night, I had to go up to the counter to see what was going on and still had to wait several more minutes before my order was ready. Beef and cheese croissant had almost zero cheese on it. Combo beef bowl was luke warm at best and beef tasted rancid. I went and bought two sides of cheese to try and help the taste. I also ordered these on the kiosk. Instead of handing me the cheese sauce, I sat and waited several minutes for it before being asked "what I needed". The small cheese sauces are a $1 a piece. One cup was full, the other was only half full. Cheese sauce was cold and goopy. Couldn't use it. Kids chicken tenders were super hard and 3yr old with all of her teeth could not eat them. They didn't include the promotional $1 slice of cake I added. When asked about it, they said they were out of the birthday cake flavor I had selected. So they just decided they were gonna keep my extra dollar for nothing?? They also left off the kids drink for the kids meal. Uncaring, nonchalant staff and gross food. Will not be back.

  First, I have to say I love Portillo's. Being originally from the Chicago area they were one of the best places to go for an Italian beef. But my visit to the Kennesaw location was very disappointing. It started with my side of hot peppers for my sandwich wasn't with my order, I went to the counter to get some and was handed a clear plastic container with "stale" peppers that smelled bad. I had to return to the counter to ask for fresh peppers, which were fine. Then, we found out that my daughter's and granddaughter's sandwiches were made incorrectly. It turns out that my missing side of peppers ended up on my granddaughter's sandwich and my daughter ended up with with sweet peppers on hers that she didn't order. By the time we were all able to sit down to eat the food was cold. We drove an hour to get there to celebrate my birthday and the visit put a really bad note on my day. Also, the music is much too loud and you must yell to be heard in normal conversation. Even though I am a fan of Portillo's it will be a long time before I make the effort to go there again.

  ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ Listen to me very carefully: Portillo's isn't just a restaurant; it’s a high-octane cathedral of flavor where diet plans go to die and taste buds go to be reborn. I ordered the Big Beef, and when they say "Big," they mean "requires a permit to transport." I got it dipped, which means this glorious weapon of mass satisfaction was submerged in a vat of liquid gold gravy until the bread reached a state of structural defiance. I added cheddar, because I’m a professional, and then crowned it with both hot and sweet peppers. The heat kicks you in the teeth, the sweet gives you a hug, and the cheddar brings it all home in a creamy, salty embrace. It’s not a sandwich; it’s a spiritual encounter. THE SIDES (OR: THE MAIN EVENT PT. 2) You think you know French fries? You know nothing. The Large Cheese Fries at Portillo's are crinkle-cut conduits for a cheese sauce so velvety it should be illegal. If I could replace my pillow with these fries, I would. THE FINALE: THE CAKE SHAKE And then... the Large Cake Shake. This is the legendary move. They don't just flavor the shake; they take an actual, physical slice of chocolate cake and blend it into oblivion. Every straw clogging sip is a reminder that humanity is capable of greatness. It is thick, it is decadent, and it is the only way to properly end the greatest meal of your life. The Verdict: If this was my last meal on Earth, I’d ask for seconds. My heart is full, my stomach is bursting, and I’ve never been happier. 11/10. Go there. Get exactly this. Change your life.

  I got home from Portillo’s about an hour ago and I’m so disappointed. The food looked so good when I saw it online and I was really hoping I would love it. I got the Italian beef with sweet and hot peppers, cheese sauce, a double cheeseburger, hotdog, and slice of chocolate cake. The Italian beef just didn’t have much flavor and the meat had a strange seasoning. 5.5/10. The burger beef had a similar seasoning but it was room temperature by the time I got home 15 minutes later. The Sautéed onions tasted like nothing, and the worker told me that they had no American cheese which was wild to me, then offered mozzarella or cheddar. I told her I absolutely hate cheddar on burgers and would just go with the mozzarella because opting for no cheese would not change the price. Once I got home I find two slices of cheddar cheese in the double cheeseburger 😑. I took a bite and was waiting for the flavors to kick in but they just felt muted. I had to add a bunch of salt to to make it edible. The hotdog was the worst part, dry, muted flavors. The cake was what I hoped to be the saving grace but it genuinely taste like box mix cake with good frosting, or sheet cake from Kroger, the most basic one you can find. I hear that the company was sold years ago and that’s why the quality declined but if you are expecting the food to taste as good as it looks online, lower your expectations. Go in there with no expectations if you want to try it but for an Atlanta native who’s been to Chicago, I know that Chicago has some of the best food in the world and I’m sure these items taste way better up there. Here in Kennesaw I will never return.
