HEy Jbthi, you fellow Hautian!
MY family has been going to Sanibel for years. Our favorite places on Captiva are:
RC Otters- great menu, good one man band that does a lot of Buffet music.
Bubble Room-huge menu, super desserts and lots of weird wacky stuff inside to entertain the kids
Mucky's- this is a must do at sunset. The problem is everyone wants to do this. I believe the restuarant opens around 4 and people are usually lied up then. They have a great outdoor patio with some musical entertainment and a little bar set-up. IT is hard to get a seat at these tables even. But it is right on the beach and is fabulous view!
The parking around these restuarants is horrible. That is half the battle.
There are lots of good places to eat on Sanibel as well.
The Lazy Fllamingo, Gilligan's, etc.
