Solid Starbucks with grade-A people working there who remember you (for the most part) when you return basically every day. This Starbucks is inside the Omni William Penn Hotel, so watch out for the ridiculous lines around 8:30/8:45am on weekdays. Some of the cashiers can be grumpy, but wouldn't you be too with loads of caffeine-starved grumpy people pawing about?
Triple grande americano, anyone? Make it a quad!
