To all movie buffs out there, if you can't find it in Quiapo, try Video 48 Plus first. They have a wide range of Pinoy movie titles, Oscar winners (including a complete list of Foreign Language Film Winners, etc.) and more (action figures, posters, memorabilia, Lino Brocka's borrower's card, etc.)
Reach them at +63-2-4150108 (and tell them "sa Video 48 po") or +63-917-3874452.
To go there by cab, kindly ask Manong Driver to bring you to Metro Bar along West Avenue. That's the best landmark I could give, since the street intersecting/perpendicular to West Avenue is not that popular (I think it's "Liwayway St."). There's a pastry shop in the corner and beside it is Mary Santos Arcade where the video shop is located at the ground floor.
