I've been getting haircuts from Mr. Luna since at least 2003 or so, I've tried a lot of other places (budget and otherwise) in the area and no one cuts hair as well as he does. Highly skilled, highly recommended.
Sometimes he has student barbers and you can get a haircut for cheaper, but still with his supervision. Call ahead about those to schedule a time. Also, if you enjoy talking about sports/cars he is probably a great barber for you. Remember to bring cash as this place doesn't accept credit cards. There is a Safeway right next door with a Wells Fargo if you do need to withdraw money.
