Photo Gallery: Now Open—First Day at Sonic Drive-In

The lights are on, the burgers are hot and the servers are skating around the parking lot at Sonic. The long-awaited drive-in style fast food restaurant .

The day was a little slow, but once word is out, business will be booming, said Joshua Barnard, general manager of the Cinnaminson location.

At around 8 p.m. Tuesday night, however, the parking lot was packed.

Servers have been training for the past two weeks and about 123 have been hired for the Cinnaminson restaurant alone. There are about 45 employees working each shift.

Barnard said several local high school students got jobs at Sonic, including those from surrounding areas like Moorestown, Delran, Riverside, Pennsauken, Camden and more.

"We want a big family here," Barnard said. "We're a bunch of locals trying to make a living."
