This could well be out of date best to actually try and call them to check there really is one, not all countries have representation in the Philippines. http://www.manila-embassy.com/portugal.html
@kingrulzuk, I don't think there is a Portuguese consulate in Manila. I met this filipina in the Greece consulate while I was applying for my tourist visa for Greece last year (April ) I asked her where in Greece she was going and she said she's not going to Greece. She was going to Portugal because her husband is living there in Portugal. As Portugal do not have any representation in Manila, the Greek Consulate cover their applications, this is the way it is done between European countries sometimes.
