Don’t put yourself through Restaurant Week withdrawal if you don’t have to. The official promotion may be wrapping up but a number of generous restaurants will be continuing to offer their discounted menus through the end of the month (and beyond, in some cases). Where can you still enjoy a 2-course lunch for $15.11; a 3-course lunch for $20.11; or a 3-course dinner for $33.11? Check the Insider’s Guide to Restaurant Week regularly for details and updates but here are a few just to whet your appetite: The Fireplace, Flora, Grotto, Lumière, Marliave, Masa, Masa Woburn, Sel de la Terre Back Bay, Sel de la Terre Long Wharf, Tryst and UpStairs on the Square.
