It’s been a banner week for new coffee shops, first with the debut of Glasser Coffee Co. in Brighton, and now with the opening of Cicada Coffee Bar in Cambridge’s Central Square. The Vietnamese coffee shop, which launched Friday morning, is fueled by Vietnamese women-owned roasters: Nguyen Coffee Supply in Brooklyn, N.Y., and Càphê Roasters in Philadelphia, Penn. The menu includes cappuccinos, coconut affogatos, and the Cicada Latte, but the honey mousse espresso, or cà phê trứng, looks particularly delightful. It’s traditionally prepared with egg yolks, condensed milk, coffee, and, in Cicada’s case, local knotweed honey instead of sugar. To eat, the cafe also has a variety of bánh mì sandwiches and pho salads, plus pastries from Butternut Bakery in Arlington. Orders can be placed for pickup here.
