That would depend on your spicy level and which dishes you choose to get from the buffet. They range on spicy levels. If it's too spicy, add some of the raita and it should cool it down.
I did not have buffet there but dishes we tried were mid spicey..bearable.
I did not eat the buffet but the dishes we ordered were moderately spicy for Indian palette.
