Agree on the facts of adultery law, poverty & crime. Lately crime getting worse, usually target foreigner but mainly chinese.
Food on the other hand, different province have difference signature but most food are the same even bakery, kinda general. Not trying to say bad about them/religion, they do tend to pray but without doing anything to make it happen, as in pray for apple to drop from the sky.
Communication part, manila and surrounding province generally do speak english but further away might not. In Cebu part, English generally in city centre but going outer you'll have tough time communicating in non tourist area.
