As maj42169 pointed out, you can't be certain there will be crab legs on the menu at Coral Reef. So don't make that your plan.
I am a big seafood lover, and crab in particular. I am from the Pacific NW, and we get some of the best crab in the entire nation. That said, Fulton's Specialty, the Crab Claws, was the BEST CRAB I HAVE EVER HAD. We split the crab claws meal, and shared their caesar (which I have to say was also one of the best caesar salads I have ever had, and asked for the recipe, which the chef wrote down for me personally!), and dessert, and it was amaaazing. So great in fact, we splurged big time and went back a second night in a row and got one full crab claw meal EACH so we wouldn't have to share (it is SPENDY, this meal, and we were at the end of our trip so low on funds, but it was worth it!!).
Our next trip will be this coming December, and we cannot WAIT to hit Fulton's and have the crab claws again. If you want crab, you simply MUST go to Fulton's!!
I will add as a final note that the service we got there was also stellar. We are not the best about speaking up about really good or really bad experiences to management (we should be better), but it was so great, we took a manager aside as we were leaving and made a point of mentioning it. And since we went two nights in a row, I can attest that the food and service were not a fluke--both nights were memorable and well worth the money!
