Simply Southern Smokehouse on Mr. Joe White Ave., has a wonderful reasonably priced buffet with the traditional Thanksgiving items, various barbecue, desserts and almost anything southern and beyond you can imagine. Food is well seasoned and not swimming in cooking oil (greasy). This employess really exemplify - "Team work makes the dream work." I'm not the biggest fan of buffets, however I do recommend this restaurant. I do advise to make reservations as soon as possible. We've eaten here several times on the big day and were here last year for Thanksgiving. We will be in Hilton Head on this year.
We've also had Thanksgiving dinner at Carolina Roadhouse, N. Kings Hwy. This restaurant will definitely require reservations for the holiday asap. Call soon if you're considering either of these 2. I hope this helps. Enjoy Myrtle Beach!
