A friend of mine is getting married in Andover in late June and is looking for a nice place for supper the night before for her extended family (approx. 50 people). Folks will be staying in surrounding towns, so the restaurant could be in a wide radius from there - even down to Boston except that driving/parking might be an issue.
She is looking for something fun (like tapas) rather than hotel-rehearsal-dinnerish, and not too spendy. Unfortunately Chinese is out of the question as the family is from Hong Kong. The Hilltop and its ilk are also ruled out. Anything else is open for consideration though.
