MILWAUKEE (CBS 58) -- Wahlburgers, in Milwaukee's Third Ward, has closed its doors, according to Hy-Vee, the restaurant's largest franchisee.

Hy-Vee cited the "changing nature of the restaurant business combined with staffing challenges," noting that they are evolving their strategy.

Hy-Vee says they will now only be opening Wahlburgers restaurants at Hy-Vee locations going forward. 

There are currently 61 Wahlburgers restaurants at Hy-Vee locations throughout eight states, and 20 additional locations are planned for this year. 

All employees at the Third Ward restaurant have reportedly been offered other positions with Hy-Vee/Wahlburgers at Hy-Vee.
