Filipinos are well-known for their hospitality and food. So bring your foreign friends to authentic pinoy restos. Kamayan sa Palaisdaan in Tayabas Quezon is one of the best. Your friends will really enjoy the floating restos there plus super yummy foods. They will experience eating with their barehands as well. There are also hot springs around the area so the 3 hr trip from Manila is really worth it.
