Just came back from a trip to Sedona...our Lonely Planet guide raved about Rene, but the 4 in our party had a horrible service experience here. The mood & dishes of the restaurant try to be classic French, but the quality of food and service were all over the place. Stay away.
However, the brunch at Enchantment Resort was even more spectacular than Lonely Planet suggested. It was easily the tastiest buffet I've been too - highly recommend bloody marys, roast rack of lamb, potato gratin and these strawberry-white chocolate parfaits. I'm not a huge brunch fan, but I ate so much that I was full for about 24 hours. Reservations required (to get past the front gate).
