Does anybody have suggestions for where the better homebrew shops are in Chicago area?

I am going to be downtown Chicago for a day this weekend and am going to pick up grains and hops for a pilsner, saison, pale ale and an Irish/Scottish ale. I have been to Brew and Grow in the Northwest suburbs and they had a pretty decent supply, but have not been anywhere else to get ingredients.

Also, any suggestion for new must drink breweries in the Chicago area?
