What is the sweetest place in manila?

Actually it depends.
If you're like the city type then Makati is a good place. It's like full of shopping and hotels etc. If you're a beach kind of person Boracay is defiantly the best, but if you don't want to be THAT far from manila you could go to Punta Fuego they have really nice beaches there too or in Sorsogon in Bicol you could like swim with the whales there. But if you're just the type who goes site seeing then maybe Cebu or Bohol is a good place.
