Tips from locals
There's a cafe right next to the bandstand, so you can grab a coffee and sit in (hopefully) the sun! (To be clear and to manage expectations, there's not often music on, but occasionally in summer.)
Try La Baita at the Clapham Common Bandstand - it does great value, authentic Italian food and drinks / snacks. It's a great spot to sit out in the sunshine
If you're staying during the summer months, you might catch a great weekend concert.
