Scottsdale or Phoenix--Upscale

I want to take good friends out to dinner at a good place, not too loud, but with excellent, food next weekend. We will be staying in Scottsdale. Have been to Christopher's and, while the food was good, the atmosphere was just too stuffy and overbearing. This was about five years ago. On that same trip we went to Vincent's on Camelback which was very good then. Is it still? Also went to Terra Cotta, but the noise level makes it somewhere I do not wish to return. Went to Roxand's for lunch, which was very good, but it doesn't look like a dinner house. Am I wrong? I am counting on you Chowhounds to help me out!!!
