Cicada Coffee Bar is a Vietnamese café by day and restaurant by night that’s been operating in Cambridge, Massachusetts since 2020. Behind the fogged-up windows of its one-room, one-story building, patrons chat over Sai Gon lattes and cured salmon bánh mì; Sea Salt Shaker coffees and phở noodle salads. Vinh Lê and Dương Huỳnh life partners and co-owners preside over the bustling operation.
