"In Logan Circle, basement bar Kingfisher made the minimum effort, slapping together a sandwich of mayonnaise and bread to supplement to-go kits of popular beer and shot combinations. Kingfisher announced Friday it would shut down entirely, but before that, owner Daniel Williams says customers had responded well. "I think our regulars are happy to help support us by buying the combo kits and six packs," Williams says, "and we’re really making inroads to the incredibly underserved mayonnaise sandwich aficionado market." Williams says Kingfisher was working on developing a build-your-own combo option that would let customers come up with their own mayo pairings. Delivery could still be in the cards for the bar. Most importantly, he says, people need to find entertainment that keeps them in their homes. He’s encouraging virtual happy hours and online hangouts." - Aparna Krishnamoorthy
