Anyone in the Worcester, MA area should check out the Crown Bakery on Gold Star Blvd.
They have a sign, when you walk in, which lists their GF items.
I recently had the rainbow cake for the first time, it was beautifully decorated, with pineapple and strawberries, and had the lightest, airy texture (kind of like cotton candy) which melts in your mouth.
Also, if you're in that area, the new shaw's on gold star also has QUITE a number of GF products, including a small GF section, which is a HUGE improvement over the last one. Not only do I not have to drive to find Amy's pizza or Mac&Cheese anymore, but the prices are quite reasonable, too.
