The food is not bad; Tainan's 意麵 (noodle) is particularly special but a bit expensive. The liver soup tastes quite good, and the steamed vegetables are of moderate portion and delicious.
The environment is okay, but it doesn't make people want to stay long; it's suitable for late-night snacks or casual drinks.
The food is served quickly after ordering, making it suitable for customers in a hurry.
The snack shop that opens only at night is a good spot for late-night food. The food is decent, and the environment is okay, but you wouldn't want to stay long; once you're full, you'll want to leave, unless you're drinking and having some small dishes.
I ordered Tainan اسان noodles, which are quite similar to Tainan's salty water bean noodle, and it's pretty unique. Those who like this type of noodles should enjoy it, although I feel it's a bit expensive—NT$45 for a bowl that only comes with minced pork and some bean sprouts.
I also ordered liver soup; the amount of liver is a bit less, but the soup is quite good. The sautéed greens are NT$40, which is a reasonable portion, and it's Chinese cabbage, with the minced pork sprinkled on top, making it tasty.
The food came out pretty quickly after ordering, making it a great choice if you're in a hurry.
