Hype. Sure.... but I like a good solid beef dipped and this spot delivers. I use to live in Chicago, and I honestly never cared much for Portillos because all the neighborhood Italian Beef spots were kinda better in my opinion. I still like to support my guys over at Super Niro's, but sometimes I just gotta hit Portillo's for it. Love the Cake Shake, the grilled Tuna Sandwich is an underrated hit for sure. I think it would be kinda dumb of you to ever go during peak hours, I hit the drive through, or take out, and find it's usually a 5 minute deal.
So yeah... do it if like it.
