Staying near Grayhawk- a couple of places close by that you might try.
1- an absolute requirement and don't dare miss it- Greasewood Flat. this place comes complete with a three item menu, a wonderful mix of real and imagined harley riders, leftover real cowboys and a lot of other people. Sit outside on a picnic bench, throw wood scraps in the oil drum fireplace and git yer own beer. Its on Alma School road near Pinnacle Peak.
2.. Just opened- a little place called "Cafe Ted" in the building on the NW corner of Pima/Pinnacle Peak (same building as Michael's). I had a nice duck confit salad, other things looked interesting too. Open til 9 at night with some nice wines by the glass and little hings to eat.
3.. "3 Tomatoes and a Mozzarella", at Miller road and Pinnacle Peak. Owned by some nice people who tell me they opened it because they could not get a good pizza anywhere in north scottsdale. Small menu, pizza, salads and paninni. Nice place.
Enjoy, and don't forget a nice hike into the McDowell Mtns to check out the wildflowers this year.
Try Norman's, Papago Plaza, and also deifnitely stop by Cowboy Ciao in Scottsdale for a glass of wine and a nibble at the bar - or dinner. For Mexican, try Richardson's or Los Dos Molinos (kitschy, not incredible food but an experience). Cafe Terra Cotta is also a stop, or if you like try, Malee's on Main. Have fun and ignore the whiners and wailers who insist you can't eat lunch (or dinner) in this town. You can, too.
