The one we went to is located inside of the Borders Bookstore inside of White Flint Mall in Kensington. I don't believe they have any freestanding stores in the DC area.
There were a lot of tables with people reading, studying and using their laptops while drinking their coffee. We ended up sitting near the magazines so we could read and drink.
We ordered a 'Vanilla Iced Coffee' and it was really good. I didn't have to add any more sugar or cream. There was no bitterness to the coffee like Starbucks is known to have. You could tell the ice was filtered because of its clarity. It was a refreshing beverage and I'm glad my friend recommended it.
Overall, I had a great experience with their coffee, which makes me want to try other places outside of Starbucks. Sorry I don't have the prices, since Evil Ben was being a gentleman. It is also nice that you can bring your coffee/food around the bookstore so you can spend a quiet afternoon eating and reading for free.
