The affordable snack shop in Ximending can be considered one of the safer bets, as this area is easy to trip up in, often being derisively called a food desert.
The oyster omelet has few oysters, a lot of batter, and is soft rather than crispy. The egg is not the main focus, but it comes with classic bok choy, and the sauce is quite good—slightly sweet and sour, with a suitable salty balance.
The turnip cake (two pieces) has a slightly charred and crispy surface, and its sweet and sour sauce mixed with soy sauce brings a savory sweetness that is fairly good.
This place serves food quickly, especially since these two dishes are continuously being fried, making it a decent choice for a quick bite, although it can't really be called gourmet.
