In China, a lot of what people eat has a lot to do with healing an ailment or keeping healthy. Instead of what sounds good for dinner, they may be thinking of how the food will make them feel, and how it may affect their health.An Dong - my instructor said An-Dong was the best place to find vegetables.
Fubonn Shopping Center also has an amazing array of spices, sauces, and even has a small pharmacy
If you are on the other side of town, my favorite is the big Uwajimaya store on the Beaverton-Hillsdale Highway.
