In Old Town Scottsdale: I recommend Kyoto Japanese Restaurant. It's a jolly good time. They have hibachi tables with charismatic chefs and the sushi is fresh and tasty.
Near Taliesin West: This is pretty close to North Scottsdale so I recommend going to the Scottsdale Quarter or Kierland Commons on Scottsdale Road and Greenway Pkwy. There are many restaurants in both outdoor shopping areas, but I highly recommend Zinc Bistro at Kierland. It's a little pricey but try the gourmet mac and cheese and you'll be delighted. It has an atmosphere rich with depth. With a French style, it's one of my favorite restaurants in town.
Desert Botanical Gardens is somewhat near the Arcadia/Biltmore area so I recommend DeLux Burger. It's hip and fresh with a nice selection of craft beer on tap.
