I've heard of unlimited chicken wings by some restaurants but the reviews weren't that great. This, by far, is the best. It's a much cheaper version too.
Paku (translated as wings in English) offers Php199.00 for unlimited chicken wings and unlimited rice. The meal is best enjoyed in a group. If it is your first time to try, I suggest that you take all 8 flavors. You can ask for the flavors of your choice later. Make sure to order enough, though. Leftover chicken costs Php20.00 per piece.
My favorite flavors are teriyaki and lemon pepper.
