Whenever we drive by the Chinatown, we usually just stay for lunch and pick up some Hong Kong style pastry. There's not much to see, but you can find most of the Asian things you need. Compared to the ones in NY and SF, Chicago Chinatown is small. The town does have some decent restaurants for traditional noodles and congees, though. The price is reasonable, some are lower than $5. Most of these restaurants still do bubble tea. If you need herbs, there are plenty of shops for that, too.
