The Nehru Centre has events on from time to time in their well appointed little theatre. Most events are based heavily on Indian culture, unsurprisingly, but quite a few are free, so newcomers and those with some curiosity should find no barriers.
The atmosphere was friendly and supportive and the event was well attended. The room squeezes in the middle so you get a sort of forced perspective view from the back which I couldn't decide if I liked or not but the sound was good and the view unobstructed thanks to the rake. Definitely worth a look if it tickles your interest.
