The Cottage Island Market and Spirits is up and running. Upscale-ish convenience store featuring an extensive selection of wines, liquor, and craft beers (mix-and-match six-packs), and Annarosa's bread (fresh on Saturday).
Wine and liquor tastings Saturday afternoons.

Emerging from the iconic Island institution - Mr Moe's - this is the second recent Island addition (following Plum Island Provisions which replaced Dick's Variety.)
