Updating from the AZFoodDude's previous story here, the Filiberto's at Talking Stick at the Scottsdale Pavilions will be opening in mid-May. This comes from the "Valley Values" advertisement in Sunday's Arizona Republic seen to the right.
Also in an Arizona Republic article here, we find that Filiberto's is taking over the location at 32nd St. and Greenway at the former Arby's spot. A quick check on the Filiberto's website, however, does not yet show a restaurant there.
Update (5-14-2011): Filiberto's to open Memorial Day weekend
Update (5-27-2011): Filiberto's is now open
