Nutritional Information of Taiwanese Foods

Is there any online source that provides Nutritional informational (calories, carbs, protein) about Taiwanese foods. I’m talking more of your street vender variety. I’ve managed to track down the odd one, but have yet to locate a few of my personal favourites local treats. Any help appreciated.
