P.F. Chang's (PFCB) said same-store sales declined last month at both its China Bistro and Pei Wei Asian Diner units.

The Scottsdale, Ariz., restaurant chain said bistro comps dropped 0.5% despite a 2.5% price hike, while Pei Wei comps slid 1.5% in spite of a 2.7% price boost. Total sales rose 14% from a year ago to $231 million, just shy of the $231.9 million Thomson Financial analyst consensus estimate.
