One of my favorite street foods in Taiwan would have to be what they call 地瓜球 (di gua qiu) or sweet potato balls. They're deep-fried yummy little balls that are a bit sticky inside. They're 20 TWD (30 PHP) for a small serving and 30 TWD (45 PHP) for the bigger one.
It kind of reminds me of the texture of tikoy. I seriously don't know how they got it to be so sticky! I try not to eat so much of it cause it's deep-fried.
