This vacant property sits at the key intersection of Petaluma Boulevard and D Street, and is directly across from Walnut Park in the center of Petaluma. This 840 square foot building houses a classic drive-in / walk-up restaurant that originally opened as PDQ in 1952, and later operated as Quinleys from 1994-2004, and as Walnut Park Grill from 2007 to 2019. The property is now owned by the El Roy’s restaurant team, but their plans to reopen it as a restaurant have stalled, and this iconic spot is now surrounded by a chain link fence.
