We visited one of the 3 Crab Shack locations in the Charleston, SC area - for those of you familiar with the Crab Shack in Tybee Island, GA, they aren't related. They did not have a gluten free menu available, however, the waitres/staff was able to get the chef to explain what was and wasn't gluten free. Being a seafood place helps - pretty much any seafood not fried was safe. I had shrimp, baked potato & salad.. nothing to write home about, but it had a nice atmosphere and the staff was nice. HAD I been willing to spend a little more money, they were having all you could eat crab legs that evening, which were also gluten free...
