The Sanibel Grill and The Timbers Fish Market are at the same address. The Sanibel Grill is more of a sports bar but the food is the same (almost) as The Timbers. We each got a cup of their wonderful hot clam chowder and each had a crunchy grouper sandwich. Plentiful and delicious. Can get crowded and a bit noisy, but overall, good. Will return.
Review Source:Sanibel Grill is our favorite restaurant on the island. It is the first place we go when we come on vacation. We spend the month of December and go there once a week. My kids and grand kids arrive after a couple of weeks and even the little ones request the grill for the  Crunchy Fish.
I have have tried the Crunchy Shrimp in literally every place on Sanibel and Captiva and you can't get better fried shrimp anywhere...their cocktail sauce is by far the best! We are on our way to Sanibel now for a week in May...tonight  I will get the shrimp! The other thing that I think is worth mentioning is the staff and management is terrific and the restaurant is totally kid friendly. It is a bar but still caters to families on vacation. Having said that, it is not bar food by any means. They know what they are doing. They have several Asian dishes, burgers and terrific salads. I am always tempted to get other dishes but  can't resist the shrimp! I almost forgot, you have to have a beer with their artichoke dip. If that doesn't start your vacation off right nothing will.
