This might be the most romantic place to have dinner in the Phoenix Metropolitan area.
Set back in the Farm at South Mountain, my girlfriend and I dined outside and it felt like we had made a weekend trip out to Napa. We even heard a pack of coyotes "yelping" towards the end of our night - it was a really wonderful experience.
As far as food goes, we tried the "Farmer's Feast" - a chef selected tasting menu w/ a wine course - and the ingredients were extremely fresh and every course tasted better than the previous. The menu is seasonal and is constantly changing; but the pate, and halibut with pancetta stuck out above the rest. Each wine was paired perfectly for each course.
This place is expensive, but you get what you pay for. Highly Recommended.
