Atwood’s Tavern serves drinks from Lamplighter Brewing and Somerville’s Bantam Cider and dishes using fish from the New Deal Fish Market and desserts with Somerville’s Taza Chocolate. The 2nd Street Cafe puts chicken from Mayflower Poultry (of “Live Poultry Fresh Killed” fame) in its sandwiches, and its bank is East Cambridge Savings.

And that’s why each business’ windows display the yellow decals of a new ECBeeA Crosspollinator campaign from the East Cambridge Business Association – highlighting local supply chains that amplify the impact of local spending.

“The importance of shopping local and supporting our small businesses is abundantly clear. What often does go unnoticed are the important relationships between business owners and how they support each other,” association leaders said in a Thursday email. “Business-to-business transactions are often the foundation small-business owners rely on to grow and stay viable.”

People shopping locally in East Cambridge and Inman Square are asked to look for the decals identifying association members as ECBeeA Crosspollinators, as well as displays highlighting the local businesses they work with.

“The Covid-19 pandemic has deeply affected the supply chain. Cambridge Street has a great history of local and independent grocers, butchers and fishmongers that are also part of that supply chain,” said Jason Alves, executive director of the association, in a press release. The Crosspollinator campaign aims “to highlight this local ecosystem that is vital to the success of our small-business districts and also demonstrate how your local spending is amplified by shopping at ECBeeA Crosspollinator locations.”
