I hate restaurants that have a piano player, especially if I am put at a table near the piano. If I am going to listen to music, I want to choose what I hear, and I don't want music while I am trying to have a conversation.
When I was a young man, gay piano bars were a big thing, especially for middle aged gay men who liked to dress up when they went out to the bars, and pretend that they weren't cruising, just enjoying the entertainment.
