This is one of many Delaware locations, and the busiest one I have tried.
The service was still quick and impeccable, and the coffee is delicious.
They don't accept credit-so be prepared.
Coffee is delicious, although a little pricey. The Powder Mill Square store is often crowded, especially in the morning. Cashiers are often a little short and snippity but not to bad. Generally good, very well known in the area and adored.3
