Sanibel Traditions on the Beach?
I go to Sanibel once a year, and I've never heard of it. It may be brand new, as mentioned. You're lucky to be at Sanibel though; there are a lot of great places to eat there. I love the Tuna steak at Lazy Flamingo, and the shrimp chowder at Green Flash (which is actually on Captiva).
I have many friends who live on Sanibel and Captiva and I have never heard any of them mention it. That doesn't mean that it is necessarily terrible. It probably had a different name a year or two ago. Many restaurants change hands almost yearly out there.
It is an idiotic name IMNSHO
