Hey, whereabouts in the 'burbs? There are a few clubs, but most can be found by hitting your local GW. The Battle Bunker, next to Bed Bath & Beyond in Lombard(on Butterfield) is the biggest and is also massive with like 20 tables, with a table and minis for every GW game made. Saturdays are regular tournaments and its PACKED, better to stop in and check for a veterans night as well. GW Orland Park(in the mall) is has good players, but is REALLY small with only two(3 now?) tables. GW Shorewood(on 59) sports 5 or 6 tables, but the atmosphere is pathetic with the normal tool G-Dub employees.
There are a couple club members on here that'll hopefully speak up too. If you are ever in the Shorewood area, me and a few veterans try to hit that GW every saturday and sunday around 1pm. You just have to ignore the endless sales pitching. =)
