I originally went to Kwik Kar by the Lake because they are conveniently located for me.  I was impressed with the clean facility.  They have a really nice waiting room as well as a room for small children to play.  They always do a quick check of the engine, and if they find something that needs to be replaced, they will show it to you and explain what is needed (like a dirty air filter). 
They will also air the tires and vaccuum your car. The staff is really friendly.
