For over 50 years, Yuan Zai Hui has hit the sweet spot (pun intended) for Tainanese who come for its shaved ice and traditional sweet soups. Fluffy snow-like flakes are drizzled with a choice of five toppings, all made fresh in-house. Among these, tang yuan mochi balls are the most popular option. Sweet soups are served hot, and there are five varieties on the menu, including the classic herbal soup with grass jelly.
