This Costco is fairly decent, I'd say. The employees are always busy but seem to be able to squeeze in enough time to help you and give a smile. The customers are a wide mix ranging from ghetto teenagers to respectable families.
The Costco food court...if that's what it is supposed to be offers fare that is greasy but agreeable. For $1.99 you can get a large slice of pizza which, aside from the layer of oil on top, actually has a good taste and ratio of toppings.
