Summer hours are back at Panda Express. To celebrate the extended evening hours, participating Panda Express street locations are offering a free single serving of Orange Chicken on May 31 and June 21, the Summer Solstice, from 9 p.m. to close.

Panda’s extended evening hours will be offered through September 1, with specific hours varying by location.

Starting May 24, guests can download the coupon for their free single serving of Orange Chicken on Panda Express’ Facebook page or website.

Panda’s Orange Chicken features bites of chicken that are lightly battered and wok-tossed in a sweet and mildly spicy chili sauce.

“With summer right around the corner, we’re celebrating the brighter and longer days of the year by satisfying those late-night Panda Express cravings,” says Peggy Cherng, co-chair of Panda Express. “Day or night, we strive to make life delicious by offering fresh food and an enjoyable dining experience for each of our guests.”
