Whenever I travel to the Visayas and Mindanao region I never fail to eat chicken inasal. I think it's the region's specialty and you'd find a restaurant serving inasal anywhere. Boracay's no different, there's Island Chicken Inasal -
and Mang Inasal and a lot of other restaurants that serve inasal. There are quite a number of Mang Inasal branches nationwide. I discovered it last year when I was in Capiz and I was pleasantly surprised when they opened a branch in SM near where I live - unfortunately they don't serve their atsara in Manila. I tried out their pork sisig (yummy!) and Sweetie ordered the bangus.
