I tried Betty's (don't let the name fool you - it is a Vietnamese salon) and it was pretty good. Very clean, attentive, beverage (including wine) and snacks offered and several different "levels" of treatment. Located in what I think was an old adult bookstore (which if that's what it was it is completely remodeled) on Pioneer Parkway by OSF offices and across from Goodwill, in front of the plaza with the blue roofs.
