✨ AI quick take
Between the cram-school streets by Taipei Main Station and 二二八公園, 綠豆蒜製研所 (Lu Dou Suan Laboratory) brings a familiar old-fashioned Hengchun dessert into a quiet alley. Alongside hot mung bean sweet soup, the menu includes wood-fired dried-longan aromas, fermented rice, snow ice and coffee. The ideas are creative without letting sweetness run wild. Whether you need a rest on Nanyang Street or want to see what a southern dessert can become in Taipei, this is a place to take your time tasting.
The name lu dou suan can confuse newcomers: despite 'suan' meaning garlic, the star is peeled mung beans cooked into sweet soup. A dried-longan-scented base becomes hot and cold desserts and drinks, with taro and sweet potato balls, brown sugar pearls and mashed taro adding texture. Tradition hasn't been discarded; it's just put on a sharper Taipei outfit.
● Mung Bean Sweet Soup with Fermented Rice
Mung Bean Sweet Soup with Fermented Rice starts with beans that are soft but haven't dissolved into mush. Dried longan gives a mellow sweetness, while fermented rice adds another aromatic layer. The fermented-rice character is more noticeable than plain sugar syrup; brown sugar pearls and taro and sweet potato balls bring alternating soft, springy and sticky-chewy textures. That assertive fermented note pushes some longan fragrance into the background. Traditionalists may need time to adjust, while those who like layers may find the bowl intriguing.
● Mini Mung Bean Snow Mountain
Mini Mung Bean Snow Mountain incorporates the mung bean dessert into a snow-ice block, shaved into fine, fluffy layers. The first impression is cool and lightly sweet, with extra mung bean dessert alongside to pour on at your own pace. The mini portion suits one person without making teeth and stomach work overtime to finish a huge basin. The drawback is practical: it melts quickly. Keep chatting and the little mountain becomes a bowl of cold sweet soup again. Have a few bites before the photos and life will feel more complete.
● Mung Bean Brown Sugar Latte
Mung Bean Brown Sugar Latte uses mung beans as a chewy drink topping. Coffee's bitter fragrance, milk and brown sugar meet first, followed by the beans' soft texture. The first sip really is unexpected, as though coffee and an old-fashioned sweet soup were suddenly assigned the same table. After a few more sips, brown sugar brings them together, and the beans make the drink filling. It isn't the cautious choice, but it captures the shop's willingness to nudge tradition forward.
For an easy introduction, start with Mini Mung Bean Snow Mountain or plain sweet soup. Choose Mung Bean Sweet Soup with Fermented Rice if you enjoy that fermented aroma, and the brown sugar latte if you're open to an unfamiliar pairing. Eat the snow ice first and add toppings gradually; don't let photo time outlast melting time.

📌 Editor's closing thoughts
綠豆蒜製研所 hasn't preserved an old-fashioned flavor as a museum piece. It lets longan aromas, mung beans and modern drinks move on together. The fermented-rice version has a distinct fermented fragrance, the mini snow mountain is fine and easy to eat, and the brown sugar latte challenges expectations. In a park-side alley, both the sweetness and the pace feel quieter than outside. My takeaway is simple: tradition can be remembered well and keep living in a different form.
