May be I overexpected :/. Review on The Rock, Indiranagar, Bangalore

This place is a themed restaurant in bangalore and I have to admit the theme is really nice.It is of rocks and caves.When I went there I called in for pre booking.We were 4 friends although they said there would be no place before 9:30 and we reached at 9 however we found place after waiting for 10 minutes.There are two floors.The 1st floor was booked for a party so we moved to the second floor which was serving buffet.Veg and Non veg both were available.Well, to be honest it was a huge disappointment.The starters were very few in number the gravy for main course was plain.Non veg had better options compared to veg.The service was below okay-ish. Desserts were not refilled. Ambiance was not very good except theme.We walked out of the restaurant with a frown.Maybe it wasn't the right day to visit the place.However we were disappointed.I suggest there are many other buffets which serve better food at the same price if you are not a theme fan then go for the other restaurants at the same price.
