Friday night at the Grove Park Inn feels like the right setting for dueling pianos. The room leans upscale but the format keeps things loose, and it's a solid weekend option if you want something interactive without committing to a full concert. The Great Hall is housed in a 1913 Arts and Crafts hotel built from actual granite boulders up on Sunset Mountain, about ten minutes from downtown. The space features 36-foot fireplaces and mountain views, with no cover charge for the music that typically runs 7-10 PM. Parking is free for the first three hours, then $20-30 per day if you need it longer.
