I have never seen loose nuts at our Costco(where they serve the cafe food, that is), and our dd has had the frozen yogurt a few times. I admit, it is a bit of a risk, but I our Costco only serves pizza, the chicken/dough thing, hot dogs, the yogurt and a berry smoothie. It is a small area, not at all what I would call a food court. So, maybe others are larger and serve more selections? Space is quite a premium, and simply not to be had around here, so we tend ot have smaller versions of the big stores.
