I love Whole Foods and I've been to many of them around the US. While the Charlotte market lacks on hard to find food items I can get at other Whole Foods, they make up for it with their Wine Loft and cooking classes.
The Wine Loft hangs over the top of the store. You can purchase a bottle of wine and have them open it, or purchase a card and try different sizes of the wines they have on tap. They can also make you a cheese plate from the cheeses in the cheese shop. At the price of the wine and cheese, this is a great deal for a night out.
They also have several cooking classes, both demonstrations and hands-on, offered each month. I've attended a couple and you get to sample everything you make so the cost isn't very much when you consider you are eating a full meal.
