Cultural Story: Taiwan Sweet Potato Teahouse leads through a historic mining tunnel that was once a vital route for gold extraction in Jiufen. Walking through this tunnel feels like stepping back into a 1950s movie scene. Inside, nostalgic and retro artifacts evoke a sense of distant hometown nostalgia. The restaurant offers breathtaking views of the bay, where sunlight, sea, blue sky, and green scenery blend together. The color of the seawater, the bay’s reflections, and the sunset create a dreamlike play of light and shadow; at night, the dark sea is dotted with the lights of fishing boats and harbor lamps, resembling a diamond-studded landscape. With its strong retro Taiwanese vibe, Taiwan Sweet Potato Teahouse serves authentic Taiwanese tea and dishes, offering a taste of local hospitality and flavor.
