I doubt this qualifies as "best" but I've been getting my pizzas lately from Sir Nick's in Elk Grove Village. Their menu says that they have two other locations. I consider it as having the "best value" thin crust pizza in Chicago. On Mondays, they have half-off day. An 18" special pizza (their special is a blend of 10 ingredients) normally costs like $26. I think that's a ripoff, but on Mondays, it's only $13 which I think is an incredible deal. What's even greater, is that it's a Rewards Network place so you get 10 miles/$ In December, I got a pizza every Monday. Since the new year, I haven't been there yet this year because of the new Idine promotion that's actually caused some of us to use Idine less (see Jailer's thread)


White Cottage Pizza in Wood Dale (and a newer location in Carol Stream) is pretty good. I used to work there as a driver ten years ago and the place was crazy. They'd have 10-15 drivers working on a Friday night so I guess people really do like the pizza there.
