The most popular Bibingka outlet in the Philippines is Ferino's. Like most big food outlets in the Philippines - it started out as a small stall but because it was so good - people looked to have one in their neighborhood. I thought that the original stall was in San Juan, apparently - according to their tumblr site, it started out in Tondo. In Baguio, the Ferino's bibingka stall is located on the parking level of Porta Vaga next to the Baguio Cathedral.
I got myself two servings ( which is really big ). I opted for the one with Kesong Puti ( Native white cheese ). I like my Bibingka sweet. Whenever I have Bibingka - I put a little bit more Muscovado sugar from our pantry since the sugar that they give out is not enough.
