For our 10 yr. anniversary, my wife and I would like to take our 6 and 8 yo boys out for a fancy meal. The problem is that the only time we have free this weekend is Sunday lunch. The only nicer menu meal they will eat reliably is steak. Our perfect spot would be Grill 23 since they have fish and veggie options as well as great steak, but they are only open for dinner.
Suggestions in the Boston / Cambridge area? Bonus points for waterfront, but not required. We're comfortable with steakhouse prices and the kids have done well at fancy restaurants in the past (Abe & Louies was our last big meal out with them).
