--- If you're looking for calabash-fried seafood, you're not going to go wrong with either Ella's, Seafood Hut or Dockside in Calabash. If you want all-you-can-eat-buffett to save a few dollars due to the crab legs, then I would recommend Crabby Mike's in Surfside. If you don't want to drive that far, hit Bennett's but make sure it's the one on Restaurant Row.
--- If you want prime rib, I'd definitely go to Chestnut Hill or Thoroughbreds. Chestnut Hill only serves prime rib on Friday's and Saturday's as well as their Sunday brunch, which is outstanding. FWIW, of all the restaurants on The Grand Strand, Chestnut Hill is my favorite. You may want to check out their Sunday brunch.
--- If you want italian, I'd go to Chianti South in Little River or Rossi's in the Galleria on Restaurant Row.
--- If you've got a large party with you and you're trying to get several of them to agree on something, just go to Flamingo Grill in Myrtle Beach or Sea Merchant's in North Myrtle Beach.
--- If you want a burger, fries, wings, a cold beer, I'd just go to Hamburger Joe's. Very reasonable prices, though you may wait for a few minutes. Honestly, Sam's Corner has a darn good burger and a great hot dog. They never close. They're open 365 days a year, 24 hours a day. Burky's is locally owned and is right off Kings Hwy in Myrtle Beach. Very underrated joint and you never have to wait.
--- You mentioned Thoroughbreds earlier. I view Thoroughbreds as a prime rib place, so if you want a ribeye the best place to go is Angelo's in Myrtle Beach. Make sure you get at least a 10-oz because anything below a 10-oz won't come on a sizzler. Tremendous quality and consistency there.
--- If you want an all-around restaurant with drinks directly on the intracoastal waterway I'd try either Greg Normans at Barefoot Landing or Filet's in North Myrtle Beach.
--- A nice, clean, very reasonably-priced BBQ place in North Myrtle Beach is the BBQ House.
--- The best place for self-serve yogurt is Menchie's in North Myrtle Beach right across from Publix. The best place for ice cream is at the Calabash Creamery in Calabash. Great family atmosphere.
--- Good breakfast joints are Dino's, The Shack in Cherry Grove and Hoskins in Ocean Drive.
Have a great time!
