Char Siew Sou is basically a savoury dim sum pastry containing char siew in it! Swatow's version is pretty decent and we liked that the crust was pretty buttery and thick! 😋 As mentioned in the reviews for the other fried dishes though, the pastry was cold when we took a bite and it would be great if Swatow could keep the fried dishes slightly warmer in the pushcarts!
