Interesting thread.
I would also suggest Mexican since that is one nearly ubiquitous food for the U.S. which is pretty non existent in Europe.
Maxwell street is probably the best way to see and smell a variety of food options before committing on any since the vast majority of mexican restaurants are pretty forgettable.
I would also add a trip to Chinatown since it is so proximal to Pilsen.
The only disagreement I have with anything posted is the Dominicks suggestion. Why not go to Whole foods given the option right up the street.
