The best part about the 7 Mile Marina is having Salty's Waterfront Grill. This is my pick for the happy hours drink deals and food discounts. They make pizza fresh and spin the crust up in the air. You should keep an eye out for the event schedule, they host all sorts of group parties.
You are going to want to go here one night for sure. We tend to go only to the places that have direct waterfront dining. It is a good spot to go after your boating day for the happy hours. It has that laid back keys style attitude because of the big Tiki Hut.
