If you look at the reviews of Portillo's, everyone from Chicago is always talking about the hotdogs, but for my friends and me, it is the beef sandwiches. This place is a little awkwardly located when strolling...not really close enough to the Loop, not really in River North, but that's ok. If it were any easier, you'd never be able to get in the door. It's that popular. This is fast food at its finest. The decor is much like you'll find at any family restaurant, and they have a huge Italian menu that will be wasted on me. When I get in the mood for one of those Italian beef sandwiches that taste like the meat has been au jus-ing all day, this is the place to go. You won't want to share that tasty sandwich, but they are huge, and if you plan to eat anything else, take my advice. Oh, and the hotdogs are pretty good, I guess.
