Santa Rosa Golf and Beach Club restaurant on the beach is usually a favorite of "seniors" and "juniors" alike. I agree with Yanni's and Don Pedros on 98 is great. My parents like it!
these are great suggestions.
also, Royal Orchid in the destin direction, if everyone likes Thai.
Amore' - for great pizza and salad.
Smiling Fish is a real local favorite - with nice outdoor seating (lunch / dinner is Friday or Friday and Sat now? not sure).
