METRO MANILA, PHILIPPINES. Kainan au Gusto is one of those restaurants that you will definitely try because of its air of mystery. If you do not look closely enough or if you are not looking at its side when you pass by it while you drive along E. Capitol Drive, it would really be easy to miss this gem of a restaurant! Those who only make the effort to go down and search for it behind the big trees would discover this place. A cafeteria-styled restaurant owned by the same owner of Cafe Juanita is what will greet you as you peek through the trees.
