Proprietor Dave Ayoob took over this little business in the Bernal Heights hippie-yuppie district last year. He's purchased tons of new movies and has plenty to say about what is good and what sucks. Ayoob and the usually cordial staff seem to know most of their steady customers by name. With luck, you might get to be Customer of the Week (COW) and have your five favorite flicks listed in multicolored chalk on a blackboard for all the world to see. And Ayoob's "Big Block" is a beautiful thing: For $50 up front, you only pay $2.50 each for 20 movies.
