Quantity over quality is best way to describe this location. It also doesn't help that during their buffet hours they rented out half the restaurant to a family that was celebrating their wedding party. This isn't the most professional thing to do, because things did get a bit hectic when you try to get food at the serving stations.
Now to the quality of the food. The curry flavor is so-so, lot of the curries are watery. The naan was excellent, but the food can use some improvement.
I'd recommend Mint, Saffron, or Mount Everest over this place. Check them out for their buffet and a-la carte meals.
