Not a huge fan of the Asian supermarkets in Chinatown but Greenland is different.
First off this place is clean! No overwhelming fish smell (99 Ranch!) or messy produce/deli sections. However, the aisles are small and hard to navigate if the store is busy. The aisles aren't organized that well either. Chips and assortments of noodles can be found all over the place. I noticed that the prices on some of the items were a big higher than say, SF Market or Seafood City but Greenland has a lot more selection and variety. For me, this super market is my one-stop-shop for anything KBBQ: The deli/butcher shop features pre-marinated bulgogi, kalbi ribs, chicken or pretty much anything you need.
But what really sets this place apart is the food court. Small eateries that make up the food court offer a great opportunity to sample some unique Korean and broader Asian food if you don't have the time to cook it up yourself at home. The sweets/boba spot offers excellent smoothies and the sushi stand serves up freshly made rolls. Definitely worth checking out especially if you are in search for a certain Korean grocery item.
