Here's a great win-win: on Thursday, grab your friends and get lunch at The Blue Room in Cambridge. Enjoy a three-course meal by chef Robert Grant and know your $35 per person is going to the Lynn Shelter in Lynn, MA to provide a warm bed, hot meal, clean clothes and shelter to someone who would otherwise go without. Yes, one of our own 30 Under 30 honorees is doing good (noon-2 PM; $35 per person; 617-494-9034).
