Sonic Drive-In je řetězec restaurací s rychlým občerstvením původem z Oklahoma City, který je specifický tím, že jíte obvykle ve svém voze. Jídlo si objednáte interkomem na parkovacím stání, zaplatíte kartou a za nějaký čas k vám na parkoviště přijede číšník či servírka na kolečkových bruslích a jídlo vám předá okýnkem. V roce 2009 bylo v USA 3500 těchto restaurací ve 44 státech.
The Sonic menu includes items such as hand-made onion rings, as well as such drive-in staples as hamburgers, foot long cheese coneys (hot dogs with chili and shredded cheese) and corn dogs. Sonic is unique in that they usually will ask what condiments customers want on their hamburger. Many items on the Sonic menu have changed recently, giving the guests healthier choices, such as removing the fried onion ring from salads and removing the Santa Fe Grilled Chicken Salad from the menu.
During its early years, some Sonic franchise locations also featured regional items on their menu. Other notable menu items include Ched 'R' Peppers (a form of jalapeño popper) and Tater Tots. The company features a mix-in frozen dessert called "Sonic Blasts", with the prefix being the item blended into the product. The drive-ins also offer add-ons like chili, cheese, and/or jalapeños, on guest's Tater Tots or French Fries as an option for a side with a combination meal. The signature item is the Super Sonic Burger.
In addition to traditional soft drinks, different flavors such as vanilla, chocolate, cherry, strawberry, cranberry, apple, etc. are available and can be added to the soft drink. Popular drinks include Ocean Water (the soft drink Sprite, with blue-colored coconut flavoring added) or limeades (Sprite with lime added.) Ades can also be made with flavor combinations. The company uses the slogan of "Your Ultimate Drink Stop" because of the 168,894 possible drink combinations. Its advertising also states that "You could have a new drink every day for the next 462 years". The true number of possible combinations is higher.
