Royal Festival Hall is a great venue on the Southbank, near to lovely restaurants and bars and Waterloo station, and flexible in terms of the concerts it hosts. I’ve seen a good mix of classical music, comedy and musicals there and would like to see more. Plus, as Rob Delaney pointed out, the boxes in the concert hall are reminiscent of the Galactic Senate from Star Wars, which is obviously awesome.
