Best I can say is that it's pretty nutty over there... but in a mostly good way. Rush hour isn't a rush so much as it's a slowly moving parking lot. Everybody I met in Manila had a working understanding of English, though television, radio, and the like is typically done in Tagalog or Taglish (a curious mix of the two... generally Tagalog with English thrown in when there isn't an appropriate native word). The water is clean, except when it isn't. Same for the local foods... most of it is awesome, except the stuff that isn't. Since everybody's tastes are different, what I did and didn't like could be totally different from you. Be suspicious of motive if anybody offers you balut within the first week of your arrival. After that, it's all in good humor
Besides that, the Philippines is a crazy mix of high tech and no tech, filthy rich and filthy poor, all within a stone's throw of everything. You'll see immaculate SUVs driving next to garishly painted jeepneys (anime was a big thing when I was there a couple years back), which itself is in front of a scooter with six people hanging on the rear fender. Most of all, though, enjoy your time there. It's one of those places I'd love to go back to sometime, especially if a vacation to Cebu was on the list
