Son was stationed at Shaw AFB in Sumter for 3 years. Never made it to Charleston, so cannot give specific locations. However, as noted several times above, try one of the low country boils. Good grub. Never went away hungry. Also as noted above, get your boy hydrated. It will get a "little sticky" in SC in July.
Finally, tell your boy "Congrats" on a significant accomplishment. Best wishes for a good work out / try out. And, congrats to his parents for raising a fine young man. Tough thing to do in the current environment.
