Previously mentioned here along with Chipotle (expected to open in July), and updated here, Filiberto's opening at the Scottsdale/Talking Stick Pavilions has been pushed back. According to the flyer pictured below, Filiberto's will now open Memorial Day weekend (5/27-5/30).
I know a lot of you out there are anxiously waiting for this location to open so keep your fingers crossed and I'll post another update as soon as I find out if anything changes.
Update (5-27-2011): Filiberto's is now open
Update (6-20-2011): Chipotle to open on 6-27
