What a great experience! Dr. Hui is kind, patient, a great conversationalist, and very knowledgeable. He explained to me the particulars of potential eye conditions I may find myself with in the future and answered all my questions without making me feel stupid. I would recommend him to everybody I know. And his exam, at $65 without insurance is incredibly affordable.
As other reviews have stated, his office is located inside the Sam's Club and you don't need a membership to see him. However, as per the sign on the receptionist's desk, the eye center next door that sells frames now requires a Sam's membership as of July 1, 2014.
