There is one in Ft. Lauderale where I live. Before Whole Foods opened, it was
the "go to" place,despite high prices and the pain-in-the neck parking, for organic, bulk spice, specialty cheeses, ethnic ingredients and so on.
I was in there recently for the first time in ages. I have been shopping at Whole Foods because the selection is so much better and the fresh flowers at Whole Foods are stunning. Anyway, so I went to Wild Oats looking for bulk spice in the bins, they have discontinued those at my Whole Foods. I was shocked at how run down and empty the shelves looked at Whole Foods. The fresh meat, seafood cases and the prepared food buffet still looked nice, but it was obvious that Whole Foods had put a serious hurtin' on them.
I don't know about nationally, but in this area, Wild Oats does not hold a candle to Whole Foods or the other local family owned gourmet shops.
Hope that helps -
