We visited the Boardwalk. Being off season, it was really quiet. Some of the places were closed for the season but still there were many shops and restaurants open to accommodate visitors.
We ate at Pier 14. Excellent food, great staff and also pet friendly. An intense rain storm hit while we were there so we spent a couple hours there to stay dry. Kyle, our waiter, was very pleasant and kept us happy with beverages and dessert while we were waiting for the storm to pass.
Even during off season, Pier 14 was bustling with patrons. When in Myrtle Beach, visit Pier 14.
