I just did a smog check on my 06 WRX and passed. I had a great experience with this location. They were quick (< 15 minutes) and the owner/technician was very pleasant, friendly, and efficient.

Plus, there's several good restaurants within walking distance to eat at while you wait.

I'll be going here whenever I need a smog check.
