This review is mainly not about the supermarket itself, but on the cafeteria inside the supermarket.
The food is pretty good. Yo6 can order pre-made food, like buffet style, and measure food price based on weight. I ordered a la carte black bean fried noodle. It was quite salty but I am quite surprised by the quantity. In addition, the price is quite reasonable. But beware, the wait maybe rather long.
