Hi. I just returned from 3 days in Sedona.
The only real culinary highlight was El Rincon. I enjoyed their chile rellenos very much (more like an omelette than your typical chile rellenos).
We also ate at Heartline (mediocre at best), L'Auberge (food was good, atmosphere too stuffy for my taste), and Yavapai at Enchantment (food also good, though very pricey). Since we were staying at Enchantment, we also had breakfast there each day. The breakfast menu is very reasonably priced, and I especially enjoyed their breakfast burrito (a whole wheat tortilla filled with eggs, feta, cilantro, avocado, and tomatoes). I'm anxious to try to recreate it back at home.
We also had ice cream one day at the Black Cow, on the main tourist drag. Excellent homemade ice cream, and a bargain at that. Two bucks and thirty cents gets you a small hot fudge sundae!
