This Costco seems a bit more friendly than some of the others in the area. I've had to interact with customer service folks a few times and each time I've been greeted warmly and treated professionally.
Store is clean, and the layout is a bit more easy for me to figure out than some of the other stores, like the one on Bell.
Pharmacy is great - if you're on any maintenance medication, their pharmacy prices are much lower than local walgreens or CVS stores.
If you're going into the dairy section, bring a jacket. It's freezing!
