When I was living in the Bay Area I took my car to Serramonte as well. I had little or no problems with their service. I also took my wife's Explorer there and didn't experience any problems. Give them a try. They should treat you good, provided they haven't changed their ways since I left the area a year ago.
Speaking of San Bruno, like Pat said, stay away from them! Believe it or not, they ripped off my buddy's tweeters from his Thunderbird while they were working on his car. What a mess that was!
