Stir-fried shiitake mushrooms, braised pork, or tuna filling is placed in the middle, and then covered with more rice paste. Once cooled, it becomes Guo Zai. When eating, pan-fry the Guo Zai in hot oil, add an egg, and it becomes a delicious and savory Guanmiao rice cake. Address: 臺南市關廟區市場北街 Hours: 00:00–23:59 Tainan
