Brindavan is a stone's throw away from Cauvery emporium on MG Road. We had the lunch meal (Rs 70) this Sunday and it was very nice. The items are unlimited except possibly the curd.
You get 3 items (curry/kootu), nice hot chappatis, followed by sambar, rasam.
Food is really healthy and you'd be hard pressed to find a drop of oil (even in the papadam !)
