Activity or Hobby centres in and around Indiranagar

Hi All,
I have a 3 year old toddler and am looking out for a good hobby centre or activity centre in and around Indiranagar. He goes to a play school in the morning for about 2.5 hours but does not have much to do to occupy himself in the evening. If any of you know of good hobby centres please do let me know.
Thanks
