Three old girlfriends are converging on Back Bay Station from points north and south for a pre-Christmas lunch reunion. Likely a Monday. Looking for a place within walking distance of the station where we can have a leisurely meal. Comfortable and not a too noisy setting is ideal so we can catch up on a lot of gossip. Any ideas for some place that wouldn't be trying to rush us out the door. BTW, we're all adventurous eaters, so any ethnicity would be entertained. Thank you so much for suggestions.
