Your family might also enjoy the Jazz Club. We've gone there twice. Once we saw a very good jazz saxaphonist and this last time, we were very lucky and saw Toxic Audio. They are a group of five singers. The only instruments used in their performances are human voices and they are unbelievably good. My DH & I sat through two sets.
Check to see who will be there during your visit. If it's Toxic Audio, don't miss it! You will all love it.
