One of the thing that we missed in the Chicago area definitely is Portillo's.
We live in Las Vegas, Nevada, and the nearest Portillo's is in southern California.
Since we are in the Chicago area, had to go to get a beef sandwich.
Two of us had beef sandwiches, one hot dog (also good), and a Greek Salad.
Always amazed by the speed of their assembly line speed. This time, the salad department did not meet expectation. The employees were so busy "catering" one of their own order, our salad took quite a while.
