Chicago Area Supplier

Hello,

I'm as green as it gets with making my own bread and here, too :) I was wondering if there are any places where I can buy flour in the far Chicago NW suburbs, preferably.  Not the usual garden variety one finds at Jewel, which seems to limit itself to bread, all-purpose, and whole wheat flours.  I'm not sure I'd need huge bags either... not there yet, but maybe soon :) Pastry flour is one I'm looking for and still unable to put my finger on it locally.

Thank you
