  Next to the mall. Friendly. Good selection of veggies and other goodies. Specializes in Korean options.

I am aware of the other stores. The above is my favorite.

Honorable mention: Pammel Grocery, which specializes in Middle Eastern and Indian food. This is my favorite non-Western grocery store in Ames. They also run Pammel Deli, the best restaurant in town.
