Corregidor is a day trip, and costs about $40 bucks or so for the tour.

There is an American cemetery there that is pretty cool to check out; thousands of US soldiers from WWII left behind there.

Makati is pretty much the nice part of town, some good spots to hang out down there in the Greenbelt Mall. Cafe Havana comes to mind.

On the weekend nights, lots of people enjoy the Fort in Taguig, some live music venues there.
