My wife and I have been going to the Whale's Rib since 1987. We used to live in the Boca area, and would frequent the "Rib" as often as possible - the fish dip, the rock shrimp, everything we've ever had there was of top notch quality.
Even after we moved away from Boca, my in-laws remained in Florida, and on any visit we made, we would make time to have lunch or dinner at the "Rib".
Parking can be problematic here, as there aren't many spaces - so if you are going to eat here, you need to be either walking, riding bicycle or bring your parking place with you ! If you get here early, or in a non-traditional eating time, it will make parking a lot simpler.
Reasonable selection of beers, good menu, friendly service staff - what isn't to like !
Prices have remained very reasonable over the years, which when you consider how most restaurants have increased their prices - it puts the "Rib" in a unique position.
