Who's hungry? For the next few days, Joe is spreading the word about Maine Restaurant Week, which celebrates the ingenuity and innovation of Maine's favorite independent, locally-owned restaurants. If you're someplace where you can see the Time and Temp Sign, you're somewhere close to a great restaurant, many of which are participating in Maine Restaurant Week by offering special menus or promotions.  And don't forget about all the great Maine restaurants outside of Portland. If you're looking to dine out this week, be sure to check out the Maine Restaurant Week website to see which local spots are participating. Bon appetit, Portland.
