I think this is unequivocally the best Asian grocery store in Cleveland. Why? Well they carry Chinese goods but they also have a decent amount of Japanese goods. The frozen foods section is good and they have a nice variety and selection of produce, all of which are reasonably priced.
The space is big, after all, square footage is not really an issue in the Randall Park Mall area. Parking is easy too. The surrounding area seems a little dicey, but is there any Asian grocery store in Cleveland where that's not the case?
On the day that I ventured to CAM I was delighted to find fresh persimmons, plump chestnuts that I plan to roast, Kabocha (Its a type of Japanese squash that I haven't been able to find since moving to Cleveland), a decent selection of Japanese pickles and Japanese fish cakes. They also had a nice selection of teas.
There is a small restaurant in the grocery store for those feeling adventurous.
