Chicago
Next time try ...
Chicago is awesome and Portillo's has the best Italian beef... well, besides mine that I slow cook all day! Yummy! When you come back and try Portillo's try their fries they have the best fries and their chocolate cake is awesome too!!!
Plus they serve beer! 
Whenever I visit a friend from out of town and I a big package of their beef to bring! It is that good! They also will ship their food to you, so if ya don't want to wait...
I enjoyed your city very much and hope to return in May when it gets warm again, lol.
And OMG, who wants to open an Italian Beef place in Baltimore? I loved Al's Beef (although someone else told me Portillo's is better). It was awesome! And Superdawg! I loved it as well. I decided against getting a steak by myslelf and ordered in a pizza from Rosanti's and that was also wonderful. Pizzeria Due and Chicago Chop House are on my to do list in MAY!!!! LOL
