Hi All looking for recommendations to host a retreat for our senior scientists (30 total) in Massachusetts, not on Cape Cod, in October. I am having trouble finding a location that offers amenities (guest rooms, AV) that does not double as a massive resort. Any recs?

Hi Ya'll! Anyone have any cool restaurant or activity experiences in the Boston area. Looking to host ~30 people in Boston for a bespoke dinner experience or activity ideally in a 10 minute radius of BOS. Appreciate any leads:)
