With customers more confined to their cars over the past year, the exterior design of restaurants, always important, has become even more so.

The restaurant space is so competitive that you’ve got to hook people as they’re driving by and give them an idea of what they can expect,” says Natalie Anderson Liu, vice president of brand at fast-casual concept Mooyah.

Exterior design is so important that it was the focus of Sonic’s new Delight design, which features larger stalls in which to park and eat, drive-thrus, and an increased focus on lighting. The first Delight store opened last summer in Tahlequah, Okla., a couple of hours from the brand’s headquarters in Oklahoma City. It features a covered outdoor patio, where guests can dine under string lights and enjoy lawn games.
