Hello my friend! The venue is actually a music shop in the city centre of Cape Town. They were holding a competition to win a guitar, where you had to come in and film yourself playing on one of their guitars (you can see the price-tag still hanging off the guitar!) and then share the video to Facebook to try and get the most views!
The video that @clairemobey then shared (3 songs - this one and two that she wrote) actually won the competition... so she is now the proud owner of an excellent electric-acoustic steel string guitar quite similar to the one I'm playing here but a bit more to her taste!!
