Review for Deadwood Mountain Grand Hotel & Casino Review For Deadwood Mountain Grand Hotel & Casino Google User May 21 '17 at 18:36 The Deadwood Mountain Grand is a decent establishment. It looked nice, seemed nice, the service was okay-ish. But the concert hall was disappointing. They need to expand it so the sound has somewhere to go. I'd describe it as a conference room with lawn chairs. Since the sound has nowhere to go, it bounces back at the speakers and the microphones and causes so much distortion that your ears hurt. Soooooo, disappointment. View full site to comment or like
