Zampa - Epping, NH
Have been a few times and it was always busy. (There's nothing like it in the area.)
They play jazz and the atmosphere is smart, hip and casual.
The service is very friendly, but also young and inexperienced (read: not trained well).
The food is quite innovative and they use fresh (local) ingredients. My take on it is they try too hard with the ingredients. It's sort of like going to a friend's house that likes to cook, but is not a professional. The quality is there, but the flavors are not spot on.
Wine list is quite reasonable.
Hope this helps.
