LifeSavor, the citywide dinner party to benefit Community Servings, is back for its fifteenth year this month. On Thursday, March 29th, the multi-part, moveable feast gets underway at 5:30pm at The Langham Hotel, where guests will gather for cocktails and a silent auction. For dinner, guests will be chauffeured by Old Town Trolleys to one of more than 80 participating restaurants to enjoy a multi-course meal from some of the city’s top chefs. After dinner, guests will return to the Langham for dessert – miniaturized versions of Chocolate Bar favorites from pastry chef Alex Luna. Tickets for the whole evening cost $250 each; tickets for just the cocktail reception cost $150 each. Proceeds from LifeSavor benefit Community Servings, Boston’s only home delivered meals program for individuals and families ill with AIDS. Call Community Servings at 617.445.7777 for more information and to purchase tickets. Some of the restaurants scheduled to participate in this year’s event include:
