Po Wing Hong has many of the little things that most people who shop at Asian stores would want. They have a huge variety of random items that span from food to tea leaves to home care items that aren't found in too many western shopping markets. Usually pretty good prices but rarely do they run specials since they're fairly good deals to begin with. I believe they now accept credit cards, but last time I checked it was still cash only. Most of the works are able to communicate in English, but of course Chinese is much more preferred.
Pros: Variety, Service
Cons: Cash Only (?)
