Normally, you wouldn't see a place in the States named like this, esp a restaurant, or else people would think you are White Supremacists. But here, KKK has a whole different meaning. It stands for Kataas-taasang, Kagalang-galangang Katipunan ng mga Anak ng Bayan. It is or was a Philippine organization founded by Revolutionists in 1892, during the rule of the Spainiards.
I haven't eaten at this restaurant yet, but I've read that they serve traditional style Filipino food with a twist, or updated versions.
You know, like Adobo on a Stick or Tilapia Shake. Nah, joke.
