We went to this restaurant twice during our stay at Nusa Dua. From our perspective it is the best teppanyaki and one of the best restaurants on Bali. First of all, thanks to its very talented chef Artha. It is not purely about quality of food (that was perfect), it is about overall experience watching the cooking process, atmosphere and taste. I would strongly recommend to go there and try their teppanyaki set regardless of whether you stay in Westin or not.
