oneiron339 - can't help you out with the immediate Ft. Walton Beach area but just east of there is Destin and Sandestin. I have been there many times and a few of my favorites are;
Busters, for seafood, can't beat the oysters at happy hour and the steamed bucket is pretty good.

Louisana Lagniappe
Hogs Breath Saloon (I think there's one in FWB also)
McAlister's Gourmet Deli (pretty good mufaletta and pastrami)
McGuire's Irish Pub of Destin (unpredictably good sausage plate)
