We have been here a couple of times for brunch, lunch as well as dinner. Every single time - the place has amazed us. They simplified their operation by making it all buffet place - so you pay a fixed price and the menu is yours. A great deal if you are very hungry and don't want to go through the traditional pain of going through the menu, ordering and then waiting for it to come.
Having said that, this place is usually crowded with a typical wait time of 5-10 mins, except on a weekend or a holiday when it can go up to 20-30 mins. Due to large seating capacity, the turnaround time is quite good for customers.
The food is amazing, especially the fresh Idlis and Vadas. Their Dosa is not on the buffet table but served separately by waiters. The sambhar and chutneys are quite delicious when clubbed with Idli-Vada and Dosas. On some days, they also have Veg Kothu Parotta which is quite amazing on its own. They also have some North Indian items on the buffet table but, for me, it is idiotic to have North Indian food in a South Indian restaurant.
The experience with the staff has been good so far. Not very friendly but doing their job very well.
Parking can be an issue since there are a bunch of restaurants in the complex and all share quite small (comparatively) parking space.
