A group of 6 of us from SF and NY are seeking the right locale for a leisurely celebration luncheon the day before two get married. BBQ lobster is on the menu for dinner, so seafood is out. Nothing too pretentious, but good wine and a varied menu is a must (some vegetarians among us and champagne/wine will be flowing). A friend suggested walking over to Sibling Rivalry in the South End, but that seems rather dark (both menu and decor) for the summer from what I've read! Any New American suggestions on Boylston or Charles Sts? Thanks!
