    Hot dogs are differnt taste is cheap, with thick skin thats a choking Hazzard. Burger quality gone. Even the bun has changed. Thin burger now. My husband complaining the beef is all fat now. Scant portion of beef for the exuberant pricing. I grew up near the original villa park location . This is definitely not the Portillos I remember Dick Portillo would not be proud how the new ownership has screwed up one of the best fast food establishments that is home to Illinois . Wonder why the new and un-improved Portillos is running commercials on TV and social media when Dick Portillo never needed to run one and or a coupon to get a customer in the door. All good things come to an end eventually. Will not patronize any location again.

    I guess it will do for Oswegoan’s but the meat quality ain’t nothing like any beef’s you will find at ANY Chicago Portillo’s! I can’t put a finger on what’s actually different about the meat quality in the Italian beef’s….but it’s missing Portillo’s classic flavors for sure! No comparison to the inner city locations.

    I have been there a few years ago and I didn’t like it a lot, for their expensive and simple food. Now one of my friends recommended their burgers, and this time I really enjoyed it. Looks like I will be back many times from now.
