Business changes are taking place in the north end of Parkersburg. Das Rookhaus sub shop and cafe will be leaving its seven-year home in the lower level of the North End Tavern & Brewery at 3500 Emerson Ave. and relocating to 2911 Dudley Ave., across from Grant's Rental & Sales. Das Rookhaus owner Sherry Dugan expects to be open in the new location on Oct. 1 and will close at the NET on Sept. 29. Dugan, who has owned the business for 35 years at four major locations, said the Dudley Avenue site has better visibility and is near the new Dollar General store, which has a steady flow of traffic. Das Rookhaus was "hidden" at the Emerson Avenue location, Dugan said, but she enjoyed her association with the NET. The new restaurant will have seating for 20 and comfort chairs, she said. The NET is moving five new tanks for serving ale into the current Das Rookhaus location, said brewer Chris Hopkins. The "tanks room" will be available for small groups to rent for meetings or get-togethers. Joe Handlan is building oak high-top bar tables for the room.
