Ooooh I love Weber's! I am drooling as I write! (sorry).
Not in the Fox Valley area but close is Busy Bee Bakery in downtown Downers Grove on Main street south of the railroad tracks. Thier cakes are awesome, very close to Webers. They are a little pricey though. The suggestion of Jewel cakes is a good one, but DO NOT get any buttercream on the cake....it is sickenly sweet. The whipped cream is very good, very reasonable priced and they are everywhere. The good thing about any of the bakeries is you can always ask for a taste cake!
