There is no waiting area in the international terminal once you exit baggage claim and clear Customs. There is a Jollibee next to the PAL ticket office where you might be able to hang out while waiting: take the elevator outside the terminal to the departure area ("upstairs") and you will see it next to the ticket office in between the domestic and international terminal buildings.

I also recall seeing a couple of restaurants and cafes on the ground level outside as you walk from the arrivals area to the taxi queue.
