Where to eat lunch en route between Charleston & Myrtle Beach Airport?

6 of us will be visiting Charleston in April. We fly into and out of the airport at Myrtle Beach at 1 pm and 2 pm respectively. Any suggestions if we wanted good food, either for a sit down lunch or to take away? This board was really helpful for suggestions while in Charleston (FIG, McCrady's, Husk, The Ordinary, Smoke BBQ and Hominy Grill all booked -- or planned when the booking window opens). Hoping you can help us out with transit suggestions. Thank you!
