This place is fantastic! Always go super hungry, and maybe with a friend you can enjoy eating several food items with because the prepared foods are delicious.
Sat/Sun the lines can be longer, but the seem to go fairly fast. We ordered the Bibimbap hotpot and spicy pork from the Korean restaurant, a couple steam buns, and a green tea boba smoothie. Everything was excellent!
Walking around the store is great too - you will find things you would not normally see in your average grocery store. And the fish selection is excellent!
