One of the famous places in the Philippines is Cebu. Seems next week, the Philippine Ad Congress will ummm... congress there. Expect tons of fun stuff there the whole week.
Although I haven't attended nor am I part of any ad agency, I just wish I was there right now. I can't categorize the Ad Congress as a famous place in the Philippines but I'd say it's one of the coolest places or event to be part of in the Philippines right now.
