This Costco has a weird set-up - it makes you understand that not all Costcos are alike. It's inside of a mall which makes it less busy than the other Costco's in the area. But the food stand is outside of the Costco and inside of the mall so the line is always impossibly long.
Also, I think the deli is lacking in comparison to the Costco's in the west valley. This would probably be my third favorite Costco but it's still awesome.
