It's a quiet and not a very touristy temple situated in Little India neighbourhood. It's quite particular, I thought, has a very subdued atmosphere, and very interesting statues.
Some halls are more colourful, some are more subtle. There is a meditation corner as well, and a little garden around the Temple.
I think it's definitely worth a visit, even if a short one.
(You can walk there from KL Sentral, that's the closest station)
