You don't say where in West Chicago you live but I lived on the eastern border with Winfield for many years. We found the best Chinese to be Jin's China at the corner of Pleasant Hill Road and Geneva Road. Their address is Wheaton but close enough for a quick run for some excellent food.
They've been in business since 1989 or so and continuously produce quality food. They have the best crabmeat rangoon. Everything is made fresh to order and they will substitute ingredients as requested. I had my last meal there in March 2007 and it was as good as my first in 1989. I've never had a bad dish from Jin's.
