A couple of our friends highly recommended " Classical School of Arts " (near Dayanand Sagar College, in Kumaraswamy Layout) -- they offer drawing/painting classes for kids & women. I believe that the instructor/artist has been conducting classes for over 25 years. A few of my friends (originally from Bangalore), grew up taking classes from this artist. Also, the artist takes custom orders for artwork/paintings. Another friend has a collection of numerous paintings from this artist.
