I've been through the drive-thru a few times because this is the nearest Starbucks to my office. It was the site of my first Starbucks "pay it forward and buy the next person's coffee" experience, so that was pretty neat.
This morning is the first time I've come inside to sit and stay a while. I was disappointed that it's kind of chilly in here, since it's cool outside... it seems like a good morning for a warm coffee shop, but I think the air conditioner is on? It's pretty early, but it sees like the staff isn't quite awake yet.
The other less-than inviting aspect is the lack of tables. There are four (and a half?) tables and a few chairs, but nowhere great to sit with a laptop. At the moment, four of Phoenix's finest are taking up three tables between them as they enjoy their morning brew.
It's tough to see from the road, but this location is pretty convenient for the south part of Phoenix. It works just fine for a mid-afternoon or early morning latte fix!
