Razon’s Halo-Halo & Palabok (Lug-lug) started in 1972 in a small town of Guagua in Pampanga. It was from the ideas of the three spinster sisters named Severina, Elena & Virginia. Originally the Halo-Halo & Lug-lug was only for the consumption of the large Razon family. But the delicate, creamy, delicious taste of Razon’s Halo-Halo spread in the town of Guagua and became a destination snack area in the province. The Halo-Halo consists only of 3 main ingredients namely Macapuno, Saging, and Leche Flan. Critic says that the simple concoction is the secret recipe for the taste and success of Razon’s Halo-Halo. And now, it is helm as the BEST Halo-Halo in the country.
