Best Crab house in Miami, Ft Lauderdale even Palm Beach vicinity

Which places would you recommend for best crab house...we've seen some ads in the tourist guides for Rustic Inn Crabhouse but wasnt sure if it was a local authentic good place or not.

We live in the DC area so we've had Maryland crabs and been to crabhouses there but would like to check out one great crabhouse in south florida area---not sure the difference in flavor, price, etc between alaskan king crabs and maryland crabs (aside from size) or other types of crabs that may be local to the Florida region.

Reasonably priced would be great, doesnt have to be fancy ;)

Thanks!!
