This Portillo's does not measure up to their brand standard. Every time Ive visited the location (3 times now - 3 strikes they're out!) something sucks about my visit.
Twice the service was a disaster... be it rude cashiers or excessively long waits for food. This last time, the dining room was a filthy mess. I've seen cleaner floors and tables in sports stadiums. It was gross to walk in the dining room, and trash was overflowing.
I'm from Chicago. Ive seen the Portillo's Brand perform much better. Either hire better staff, or better people to manage the staff.
Portillo's Champaign needs to be better all around: Clean your restaurant. Be polite and professional as I hand you my money to purchase your product. Shake a tail feather and have my food ready promptly.
