Northeast Radio SD News – Sioux Falls, SD – Tropical Smoothie Cafe will officially open its first Sioux Falls location on Monday, Nov. 16, 2026, at 7 a.m. at 4417 E. 57th St., near Bahnson Avenue. The fast-casual cafe is locally franchised by South Dakota operators Angie Yahne of Watertown and Ann Park of Brookings.
The Sioux Falls opening marks the latest step in statewide expansion for the two South Dakota business owners. Park opened the Brookings Tropical Smoothie Cafe in 2021, and Yahne opened the Watertown location in 2023. The pair partnered to expand into Aberdeen in August 2025 before bringing the brand to eastern South Dakota’s largest market. According to the announcement, the co-franchisees plan to open multiple locations across Sioux Falls.
“We’ve seen firsthand how much communities in Brookings, Watertown, and Aberdeen love having a fast, fresh alternative to traditional drive-thru fare,” Yahne said. “Sioux Falls has been at the top of our list, and we’re thrilled to open our doors on 57th Street to serve guests looking for great food, made-to-order smoothies, and welcoming hospitality.”
