If this place is close to you, it's a great deal. Ask for the Yelp pricing. It was $30 less than…read moreother competitors. I only found out by doing one of those Yelp quote requests (from various competitors, did it sheerly by accident trying to make an appointment at a prior place I went to). It's a no frills place. No appointments. Walk-ins only. We were lucky in that the person before us was just finishing up when we arrived so we didn't have to wait too long. The waiting area is a few fold-up chairs in a square concrete area that is quite sloped.

There were 2 cars in front of us when we went, and they still got us out of there quicker than most smog joints. Waiting room is clean, if stark. There's a bathroom if you need it. But man, the music was SO LOUD. Like, the receptionist was yelling over the music, "OKAY, SIGN HERE!" and when she grabbed the remote, I presumed it was to finally turn the music down. Nope. She just changed it from '00s pop to contemporary country. There's an option for a tip at checkout, which always makes things nice and awkward, regardless of tip level.
