Well, there aren't many places that let you bring your own wine to the table in Phoenix, and the food is great as well.
Coup Des Tartes has a distinctly Napa Vally feel to the ambiance. The food is very good, though not among the best in Phoenix, and reasonably priced. A truly fun and magical place to take someone special.
You have to try it for yourself! One of my favorites for a nice, slow, date.
