If you're looking for an Asian store that has food from different Asian cultures such as Chinese, Japanese, Korean, Thai, Filipino and others, check out Yim's Asian Supermarket on Rock Boulevard. A friend of mine took me there and since then, it has been my favorite Asian market in the area.
They have sauces, snacks, fresh produce, frozen foods, ice cream and some prepared food as well.
If you have back pain, I would recommend buying the Salonpas Hot from there. It's a patch that you stick onto the painful area and it relieves the ache. I've tried it and it really helps!
