Five Bites Cupcakes is setting up shop at 141 Linden St., suite 2C, near LINX on Tuesdays-Saturdays. Hard to imagine it would take 5 bites to gobble up these treats, which are trans fat-free and feature specially made creams and frostings. Lots of cupcake flavors, including coconut, chocolate peppermint and carrot. The business is run by two Natick women, one an expert baker and the other an artist. A heads up: Cash and check only.
