This Costco in particular is large and the floor schematic reminds me of that of the Costco locations in San Diego. The perishable departments are logically lumped together instead of sprawled apart, so you can visit dairy and then hop next door to produce.
Like all Costcos, you can expect large quantities and discounted prices. But, it's no secret that you'll be walking out of there with a bill close or in the triple digit dollars. Bring a shopping list and stick to it!
