As an occasional visitor (work-related) to Pawleys Island and Litchfield (south of Myrtle Beach), I was looking for an inexpensive lunch spot that had decent food. (Dec 09) I found Pizza Grill-a, next to my favorite coffee/espresso shop in the area, Latte Litchfield in the Litchfield Plaza Shopping center, on Ocean Hwy. ( Route 17).
I highly recommend their tremendous meatball sub. It had some of the best home-made sauce and meatballs I've ever eaten. They serve Amoroso rolls (from Philly). They have the usual chicken turkey, BLT, as well as vegetarian subs. Subs run from $6-8, for a 6 or 12 inch roll. Generous portions served.
They also have pizza, salads, and buffalo wings.
BTW, Latte Litchfield next door has excellent coffee, espresso and deserts. Also wireless internet.
