The 1,111-square-foot shop will open this summer in a vacant tenant space at the corner of North Bayshore Drive and West Northshore Drive, across the street from Gap. It’s a second location for SereniTea, which opened in 2019 at 1414 W. Wells St. on Marquette University’s campus. SereniTea serves a variety of tea-based drinks, including its signature bubble, or ‘boba’, tea – a Taiwanese drink that includes freshly brewed tea, milk and chewy tapioca balls, known as pearls. Its menu also includes fruit teas, smoothies, shakes and slushies.
