I haven't been to any of the following places but did find them after a search; perhaps others can give first-hand feedback.
Biggby Coffee - 21 S Dunton, Arlington Hts
A smaller chain. Think it used to be called Beaner's Coffee.
That Coffee Place - 28 E Northwest Hwy, Arlington Hts
X Press-O - 195 W Rand, Mt Prospect (near Rand & Elmhurst intersection)
Gale's Coffee Bar - 601 N Milwaukee, Wheeling
The two roasters I know if in the NW burbs are
Conscious Cup in Crystal Lake (full cafe) and
The Expresso Shoppe in Bensenville (limited hours tasting room). Conscious Cup is out of your way but worth a stop if ever in the neighborhood. I just found out about The Expresso Shoppe so don't have any info on them other than what's on their website.
HTH.
