This is a dueling piano bar, and if you've never visited one, you definitely have to stop here! Basically, two pianists sing whatever the audience requests, and they are incredibly talented and entertaining. It is not your typical bar - lots of fun for young and old alike. As older twenty-somethings, my wife and I are no longer into your 'bar scene' - but the Big Bang is one day that we continue to visit a few times per year! Again, if in downtown St. Louis....visit the Big Bang!
