Located near the Cultural Road Roundabout in Chiayi City, Gu Yi Mung Bean Paste Specialty Store is in an area known for intense competition in mung bean paste offerings. Gu Yi’s specialty is their large cups, thick texture, and affordable prices.

The "Mung Bean Paste with Milk" has a very fine texture, with absolutely no rough grains detectable. This must be the result of long hours of blending. The milk and mung bean paste blend naturally, enhancing the sweetness of the mung beans to become rounder and smoother; it’s not monotonous. Each sip reveals a subtle interplay of bean and milk aromas, creating a smooth texture that makes you think, "I want another cup."

A large cup costs only $45, and it is quite filling. Since the portion is genuinely substantial, one person might feel overly full after finishing it.

Gu Yi Mung Bean Paste Specialty Store is highly recommended for its cost-effective beverages: large cups, rich texture, and fine consistency, all at a super affordable price. For tourists, this is a drink that represents Chiayi's "simple yet genuine" snack culture; for locals, it is a daily affordable delight.
