A bit of India right in London, the temple looks like it has been there for hundreds of years. The carved white marble is not only stunning on the outside, but the inside is even more breathtaking. Def worth a look during visiting hours (free) and there is a very good informational area on the history of Hinduism (small charge). There is a small shop inside selling Hindu books and devotional objects. Be prepared to leave your bags in the car or at the security booth across the street. Small bags for money are allowed. There is a security scan and you will need to remove your shoes, but areas are provided for this. The mandir is upstairs, but there are lifts for the less abled. People are extremely friendly and welcoming and if you're a fan of Indian food, check out the temple restaurant, Shayona, which is located in the car park. It's my current fave Indian food in London and it's completely vegetarian. I've been told that they make everything fresh within 3 hours of serving and you can certainly taste that. All in all a nice afternoon out for a bit of culture/history.
