There's three different ways I've judged the different Starbucks locations over the years.
1. Speed of service
2. Quality of their brewed iced coffee
3. Friendliness of the staff
This Starbucks was the definition of mediocrity. The baristas were numerous during the day time, but everyone still had to wait an extended period of time for their drinks.
Their iced coffee was okay, perfectly acceptable.
Their staff, at least the one who rang me up, was not the friendliest. She dropped a couple of pennies that I gave to her on the floor, and then had the gall to think I short changed her. Minor transgression, but definitely a little annoying.
One plus though, is that they have very different pastries, much more upscale than the normal Starbucks fare.
