Why do Filipinos go to ethnic restaurants just to order the same tapa or fried chicken and sweet-sauced spaghetti they get everywhere else?

(Note that I grabbed this image of tapa from the Max's Fried Chicken restaurants website.)
Why is it that Filipinos know all the latest songs, lyrics, and the dance moves, but radio play lists haven't changed since the Marcos era, including Kenny Rogers' Through the Years and Mary MacGregor's Torn Between Two Lovers?
Am I the only one disturbed by the Placenta line of beauty products?

These are just some of the things I wonder about.
