City Lights is pretty good but my favorite spot is Caviar and Bananas. Like a Dean and Deluca but a little more fun. Coffee's by Counter Culture, pulled on a GB5. Legit.
KuDu is also the jam, last time I was there they were using Krankies, a small roaster out of Winston-Salem. The coffee was pretty good but the ambiance was fantastic.
There's also a cool little bakery called Baked (original location is in NYC) using Stumptown - http://bakednyc.com/page/locations/
Cheers mate! Be sure to let me take you out for a beer if you're cruising through Raleigh / Durham!
