Viet Hoa is the Fiesta of Asian supermarkets and a pure delight for seekers of groceries and colorful oddities alike. It's big, it's clean and on any given day, you can find silk flowers, flip-flops and thousand-year-old eggs within a few steps of each other. The back wall is covered with tanks full of unusual sea creatures and case after case of fresh fish. If seafood isn't your thing, the array of roasted and barbecued meats could turn a vegetarian carnivorous. On the way out, a dizzying and attractive selection of jellied products is tempting enough to make you want to eat white fungus and mung bean...and like it.
