One Soy 一豆 is a soy bean stall at Punggol Coast Hawker Centre, 84 Punggol Way, unit 02-K88. It is best known for its soy milk, which comes in flavours such as taro and watermelon, and sweetness can be adjusted to taste. The stall also makes beancurd, including a pandan-azuki version and a traditional one, and rice balls. Customers praise the taro soy milk as wholesome, and one regular always orders the bandung soy milk. Another says the pandan beancurd is the favourite of the household. Some find the prices a little higher than the soy stalls in older coffee shops, though one reviewer says the prices match the area. The stall can be busy at weekends, with queues at the peak. Among the nearby dairies, HOSEH Global is 0.4 km away with 4.3 from six reviews.
