Girls' Trip to Scottsdale - First time visitor!

Hi,

My 9 favorite ladies and I are coming to Scottsdale for my 'stagette' (I hate to even use that term, as we are all in our late 30's and most of us have kids)!

I'm looking for some advice on a few restaurants while we're there (May 24th-31st). We are staying in Kierland, but only because there are houses in this neighborhood large enough to sleep all 10!

We are looking for restaurants and lounges with a cool vibe. Quality of food is important, but style/type is not. The only thing I know we all want to eat is Mexican...are there any hip joints that serve authentic Mexican cuisine?

ANY other recommendations would be greatly appreciated....bistros, tapas, etc. We are looking to keep things casual (with $ ranging in inexpensive to mid-range), but want one more upscale resto for the Saturday night.

I'll peruse this board while I wait... ;)

Many thanks in advance!
