Awesome coffee and doughnuts. Customer service is amazing too. They are not robots like other places... (Friendly humans, great attitude).
Order a nice iced coffee and enjoy it outside with a friend. It is great ambient i guess. Not a tacky starbucks ambient, more open and hip?... And affordable.
I recommend the vanilla bean iced coffee, with the sugar and creamer. It is really good. And keeps you going. After all, America does run on Dunkin. :)
