The Starbucks at 66 Crowfoot Terrace is the one inside Chapters (there's also one nearby at Safeway, and another self-standing location closer to Nose Hill Drive). I get a total kick out of coming to this Starbucks... time it right and you can see the "Yummy Mummies" let their children run wild around the store while they sip non-fat lattes, flip through unpaid magazines and even use unpaid books as coasters! If you ever feel guilty about paying $4 for a coffee, come here and witness true entitlement first-hand.
Overall it's a good Starbucks, though. I've been at least a dozen times and they've never made my drink incorrectly or made me wait for long. It's always clean and you can't deny that it's nice to sit down for a coffee with a freshly-PURCHASED newspaper, magazine or book!
