I used to be a big fan of Tonto. In particular, the salads and other vegetables were well-prepared and unlike other restaurants a great deal of care was taken to make the vegetables unique and tasty. Sadly, that quality no longer seems as high. Everything is still good, just not worth a unique trip. Plus, it's kind of pricey given the level of food.
That said, there is nothing better than looking out from their patio while sitting in the sun. Definitely, a five star setting.
