Please no Starbucks. Starbucks is consistant, yes. Consistantly bad, made out of medium quality beans that are burnt. The biggest problem with DL coffee is that it is weak. This is probably because most Americans like weaker coffee. They also use cheap beans. All they need to do is get a better grade of bean, and double the amount they use per brew.
Jazz Kitchen Express has the best coffee at DLR, IMHO. Their French Roast with Chicory is awesome with a bag of beignets.
