This Starbucks has a great, solid atmosphere because of the spacious second floor.
The seating area on the second floor has upright chairs, bar stools, and lounging chairs. It's a pretty cozy area, and there's a small closed off section at one end if you want a quieter area for work. I get my drink, take my laptop upstairs, and I get a lot more done in a couple hours here than most other places. The air conditioning can get a little cold though, so I don't end up staying very long if I order an iced beverage.
The staff here is always friendly. Great spot!
