I'm coming up from DC. I have one night in Boston. I expect to have a long hard day, after which I want to wander over to the bar (or a small table) at one of Boston's finest restaurants for dinner and wine by myself. Price is no object, nor is cuisine, but I'm looking for a place that would be the one you would pick if you only had one night and could go anywhere you want. I'd kind of like to stay around Beacon Hill/Downtown but could be convinced to go further if it works out that I have time.
Here are some I'm considering, but steer me another way if that's what you think --- No.9 Park, Clio, Locke-Ober, Craigie Street Bistro. I've been to Hammersley's already.
