The Vasantha Bhavan Food Waves restaruant is in Nungambakkam, the ground floor of the Snow Bowling building.
It is a typical vegetarian restaruant, where you can get both south and north indian cuisine.
The ambience is good, the service can be a little better. The pricing cannot be termed economical, but is definitely not expensive.
The food is good. They have a good variety of side dishes. Try Veggie do pyaaza and paneer butter masala, both are good. There is a dish made out of cauliflower, but is shaped like a chickens leg piece. It is innovative and good.
Starters especially the baby corn items are a must try. The various biriyanis - esp. the chettinad one - are good.
There is nothing different about this restaruant, but it is definitely worth a try.
