Balut

Although I haven't (and probably won't) tried eating this traditional Filipino snack, it's very commonly found here in the Philippines. Even the local 7-11 stores (there's one on almost every block here in Manila) will have balut near the cash register. Like a quick bite on the go as if it were a candy bar. Locals really like it and think that it's good for your health. Some even say that it's like viagra for men. Others believe that it's a cure for hangovers. Sure enough, I found this video below:
