The City Council on July 16 is set to open a public hearing on the proposal by Dave & Buster’s to locate one of its restaurant/entertainment establishments at 275 Mishawum Road. The hearing was originally set for last Tuesday but was rescheduled at the applicant’s request. The Dallas-based chain, filing under the legal entity Dave & Buster’s of Massachusetts, is seeking three special permits. The proposed location is part of the former site of an MBTA commuter rail station. The Planning Board, which will make a recommendation to the council about the project, was set to open its hearing on the plan last Tuesday, according to Edmund Tarallo, the city’s planning director. He said with funding provided by Dave & Buster’s, the city has hired a consultant to review a traffic analysis prepared by the company. He said the Planning Board should have the results of the consultant’s review when it resumes the hearing on Aug. 6, and is likely to make a recommendation that night. The council, which also meets Aug. 6, could take action on the project as early as that night.
