Diversified Restaurant Holdings, Inc. (NasdaqCM:SAUC) is seeking multiple strategic options for its Bagger Dave's Burger Tavern chain. It said the decision to explore options for the unit follows Diversified last year focusing resources on developing and expanding its Buffalo Wild Wings franchises while right-sizing the Bagger Dave chain. The company said it makes no guarantee it will complete a deal for the unit, adding it does not intend to provide investors with updates unless there is a proposed transaction or the process is called off.
