Huge Asian Grocery in Cranston RI?
Could it be Chinese American Mini Market, 834 Park Ave. (near Rolfe) in Cranston? As the name implies, it is not huge, but it is the largest Asian market that I know of in the area. They have a big variety of dry goods, preserved items, fresh veg & meats, etc. They also feature many frozen specialties which are otherwise hard to find, like pig blood and beef blood (think boudin noir & black pudding).
There is a tiny parking lot next to the building or you can park on the street. They speak enough English to be helpful.
