Why didn't I know about this place? I found out about it from the Alton Browncast, a podcast that I highly recommend. The factory store is located just off the perimeter. It's a real factory, so the location in an industrial park is pretty low key.
I wasn't sure what to expect, but the store features tasting and to-go pints of ice cream; don't expect to drop by for a sundae. I tried three flavors. The banana chocolate had a wonderful banana taste; the coffee was a much more subtle coffee taste than I've ever had in an ice cream; and the vanilla sel de mer was sublime. In addition to superb flavors, the texture was perfect.
I happened to visit during a factory tour, so I hopped on. It was led by the chef and very enjoyable. This is very much handcrafted ice cream. They also spend a lot of their time on custom orders for local restaurants and we heard some very interesting stories of unusual requests. We also got to try yet more ice cream straight out of the machine---soft and rich, reminiscent of soft serve but so much better.
This is truly great ice cream and the factory store experience is well worth the trip.
