A spacious cafe with plenty of shaded patio space that's always open early right at the entrance to the Arizona center. It's a great place to study and the crew is very friendly to their customers.
This location sees a ton of traffic due to its closeness to the Sheraton, AZ Central/Republic, APS, the Convention Center, and the whole Phoenix Biomedical Campus, so mornings after 7:30 it gets busy. Last week I witnessed the perfect storm when the convention center opened it's doors to both the national origami competition and some odd bedazzle jewel craft competition, so this starbucks experienced an onslaught of 30-40 something women all scrambling for their mochas and bagels simultaneously, completely choking the wifi connection while they wait in line playing candy crush or pinning hot glued denim accessories or whatever it was they were up to. But despite the long lines (especially when there's some event at the Convention Center) they pump people through here quickly and you'll usually see the GM himself in here himself working harder than anyone else, greeting and assisting with the order for each customer.
For the volume of traffic this location sees every day, you have to admire their efficiency and the fact that they manage to maintain a good atmosphere.
