Grounds for Expression is a nice, laid back coffee shop located just outside the front gate of Seymour Johnson Air Force Base on Berkeley Blvd. They have a nice selection of hot and cold drinks to choose from, and even have drink selections for people who don't care for coffee. They also have a good selection of bakery items such as pies, cakes, cookies, etc.
Grounds for Expression is also reasonably priced (as compared to other coffee shops in the area). One nice incentive to go there is the frequent buyers card. Using this card, if you buy 10 drinks ($4 and up), you get the 11th free.
As far as entertainment, they offer computers to access the Internet and special events such as poetry readings, small concerts, etc.
