Another post from the local food and coffee snob...
If you want REALLY GOOD coffee, you NEED to make a visit to Crescent Moon in Mullica Hill, NJ:

It is only 10-15 min (depending on traffic) from Four Seasons and has the best coffee in the Philadelphia area. The owners themselves travel the world to get the best coffees, they roast all their own beans, and the baristas are all well-trained and artists in their own right. They also supply their beans to Whole Foods and many other area coffee houses.
If you want to go to somewhere a little closer to Four Seasons that has good coffee, try Progressive Coffehouse right here in Glassboro:

It is a local hangout for Rowan University students and faculty and also has good coffee, but they don't roast their own beans.
Both places offer coffees that are far better than Starbucks IMHO...but hey, I know that 'bucks fans are almost as dedicated as Cathe fans!!!
