3 day weekend. Seafood & activity recs?!

My husband and 12 year old will be in Myrtle beach Friday sat & Sunday. We haven’t been to Myrtle in years!

My daughter is a crab leg addict. Looking for the best spots for seafood/crab legs in Myrtle beach? I looked on TT but see so many mixed reviews in not sure. We also love a good steak & sushi. & coffee shops! Haha

Lastly, apart from the beach, any fun things to do to keep our 12 yr old entertained?

TIA !
