I'm not from Chicago, never been to Chicago (although it's near the top of the list) and never heard of Portillo's before it opened up in Scottsdale, so I'd say I'm pretty unbiased. Tried the italian with sweet and hot peppers and gotta say: it was damn good. I might get it with extra gravy next time because it might have been a little dry, but other than that the meat was great, the peppers were great, the bread was great. My gf had the chili cheese dog and she was impressed. The place is packed, but things move along rather quickly. I have a feeling this is the kind of place I'll be craving.
