We have been going to the Continental Cleaners in the Costco marketplace for the past few years. This is not the main location, but it's convenient if you live on this side of Chino Hills. The price is comparable, actually fairly inexpensive. The only problem is that they seem to close earlier than some other dry cleaning locations. But the service is great, very reliable. Would still be using them if we lived on that side of town! The other location is in the old Sizzler area in Chino Hills, I believe.
