Here's a hefty sized burger from a place in the Philippines! The place is called, "HungreeBurgers", has 3 locations, and sport what I would assume to be some of the largest burgers in the Philippines. 8" diameter is pretty good for a readily available fast food burger! This vid shows the making of, and a few pics of the burger itself. Not sure if it's a commercial, an ad, or what... the music is pretty groovy though...
