Permit requests are being processed for Walla Walla’s new Sonic Drive-In.

The city has received applications for construction, along with plumbing and fencing for the work at Walla Walla Town Center.

Under the proposal filed by contractor Dimensions Inc., plans include construction of a 2,317-square-foot restaurant with 1,388-square-foot canopy.

An opening in spring has been the previous forecast. Zelman Walla Walla, which owns the property, says nothing has changed from that projection.

Sonic is the country’s largest drive-in restaurant chain with 3,600 locations and its signature retro carhop service. Its eclectic menu covers everything from burgers and hot dogs to breakfasts and specialty drinks and treats.

The Oklahoma-based company was purchased in a $2.3 billion deal by the parent company of Arby’s and Buffalo Wild Wings.

Atlanta-based Inspire Brands completed the acquisition in December. Inspire became the fifth largest restaurant company in the country with the purchase.

The new Sonic in Walla Walla is slated for 1553 W. Rose St.

Zelman Walla Walla said other potential tenants for Walla Walla Town Center have circled, but there is otherwise nothing new to announce for the retail development.
