It's a little stinky, and the layout is mixed and odd, but for convenience, price, and sweet service, I come here damn near weekly. Most of the produce is of Mexican/Chinese source, so if you aren't a GMO fan, this is the wrong place to shop. However, what you lose in evolutionary purity, you make up for in price: Roma tomatoes, in the middle of winter, for $.49 a pound. And they were almost as good as they were gassed to look.
The Mexican groceries are (obv) where this place excels. Quite possibly the most comprehensive collection of dried chiles I've seen in Charlotte. 3-4 brands of pickled jalapeno to choose from. Tortillas of every kind in abundance. Entire fridge case of Mexican/Latino cheese and dairy, in a range of quality and price. One isle is devoted to Asian products and canned goods, and most of your classics are there: Huy Fong sauces, coconut milk, curry pastes, noodles, at the same prices you'd pay at Overseas or International.
What's interesting is that their standard grocery section is a bit overpriced: for frozen pizza, snacks, pet food, etc, you'd be better off across the street at Food Lion.
