I recommend you get the fuck out of the city, at least for a few days. Manila's interesting but there's so much beauty and so much to do in Philippines, and Manila is still just a massive dirty city, as over the top as it is. There are some decent dive spots on Luzon (and you can get your open water certificate for like $350), and the mountains of North Luzon are supposed to be awesome for trekking.
In Manila I stayed in Makati and checked out a club called Bureau which was decent. Another one was called Embassy (though I think they changed the name -- but it's in a complex called "The Fort"). That seemed to be the most upscale place where all the rich people go. So you get the hot high society girls and shit. Kind of hard to get in with them sometimes because they're there with big groups of guys and girls, but hey it's worth a try. Easier at Bureau, but quality's a bit lower. There are clubs in the Ermita and Malate areas too, but there's a lot of hookers in those clubs so you have to constantly weed them out which can be annoying.
In Cebu City (on Cebu island, not Manila) I pulled at clubs every night. If you happen to go there check out Mango Square, there's a club called Juliana's, another called BEAT, and another one Pump 2. Easy pickings but a bit ghetto and the clubs are dark as fuck so you have to make sure that chick who starts grinding her ass against you is not a ladyboy. Something slightly more upscale was a place called Voodoo (not in Mango Square).
I just got back from the 'Pines. Awesome place.
