When I did a search for Korean market, this is the only place that shows up in the area. They were definitely no H-Mart from Cali, but it was the best they got in town. The place was quite big with a modernize design located within a complex with a mini strip mall before you reach the grocery store. They even got a post office here.
Size is about the same as other ethnic grocery stores like 168 and Ranch 99. They do have a large variety of Korean products here, like the Korean paste had over 20 plus choices, and tons of brand for soju. They also have small boxes of the fresh Korean small dishes for sale here.
I would definitely recommend Greenland Supermarket if you are into Korean products. The staffs were very friendly too.
