We tried their sour vegetables 酸菜 fish soup which delivered the sour kick with a light spiciness, like that of a Szechuan sour. The sliced fish was really fresh we liked that they added some flower petal (think so) which have some pleasant fragrance touch.
Other options included Mala or even Tom Yum soup with seafood or beef choices. Non-spicy alternatives were available too though their selling points seemed to be on the spicy dishes.
We loved that all their dishes were served in a hot iron bowl which retained the heat well especially for the spicy soup. Though just a foodcourt stall, the soup with a rice was a satisfying meal. With the portion, it was good for sharing for some too.
