I've been eating out a lot here. My comments on some of the places.
Indi Joe: Bang opposite to my office and hence most of the group lunches happen here. Their buffet costs Rs.425 and heard that the menu remains almost constant. Not worth the money, especially if you are vegetarian. I enjoyed the Fig pudding though..

Royal orchid park plaza's limelight: this again is close to my office, but landed up there with couple of our friends from US for dinner. It is also buffet costing Rs 500 (inclusive of taxes.). Spread was excellent. South indian karela fried, koottu, poriyal, salad spread are worth mentioning. The rasamalai was really yummmmmmyyyyy.

Parika, Indiranagar: Had ordered food from there for dinner at a friends place. Pretty decent food.
