I stopped by Ananda Bhavan for a quick, enjoyable snack. The Sunnyvale location is located near the Sunnyvale Fry's. It is one of several locations in the Bay Area. The decor is unpretentious and the hours are pretty long, befitting a restaurant that serves chaat.
The photo of my vadawasn't saved (damn you, Android!) but I love those tasty lentil donuts. This photo is of my mini idli. I would compare them to ravioli but they don't have any stuffing. They were very satisfying, with just a bit of kick in the sauce.
