when does sonic start serving lunch

Sonic starts serving lunch as soon as they open, typically around 6:00 AM, but the official transition from breakfast to lunch menu happens at about 10:30 AM. However, Sonic's full lunch menu is available all day from opening until closing, which is usually around 10:00 PM to midnight, depending on the location. This means you can order lunch items like burgers, hot dogs, and chicken sandwiches anytime Sonic is open, even in the morning.
