The Take
Portillo's Italian Beef posts a Slop Score of 29. The slow-roasted whole-muscle beef with house giardiniera nails the classic Chicago sandwich while the default fries and chocolate cake push the meal toward industrial mid.
Single-protein focus keeps shortcuts minimal. Chain scale still dilutes the edge that made the original stand out.
The Verdict
The beef itself stays based. Everything else on the tray leans mid.
Order the based version and skip the sides. Slop Score 29.
