This is a good night to check out the Arena Stage Piano Bar because it will start a little earlier - 9pm. I've been to most of these and they're always a blast. We're not talking karaoke here. Yes, anyone can sign up and sing, but they get a lot of musical theater people so the talent is impressive. There's a nice bar and a beautiful view of the Southwest waterfront. Admission is free. Some of us will be coming over from the Environmental Film Festival at the Canadian Embassy. Oh, they have a Facebook listing for the Piano Bar.
If you've never been to Arena, you will be very impressed. The Waterfront Metro on the Green Line is just a couple blocks away. Street parking will be available but you'll need to feed the meters until 10 pm.
