We are celebrating a big anniversary with a day in the Berkshires. We plan to take in Mass Moca (maybe also the Clark Museum if we're not too exhausted) and then see a play at the Williamstown Theater in the evening. We are looking for a resto in the area with (hopefully) great food, but since we're going to the theater, not a long drawn out production. We are open to any cuisine, but ideally would like a place with a locavore-ish sensibility.
Also, if someone could recommend a place to stay that is pleasant and clean, but not too fancy as we will not be spending time there other than for sleeping.
