Visit to Port St. Lucie
In the St. Lucie /Stuart area, for fun and seafood I recommend Conchy Joe's, 3945 NE Indian River Dr in Jensen Beach. Lots of Old Florida flavor. If you can, get a table near the water in the evening when the bridge is lit up. Order the conch chowder & the mango plantains. Great raw bar, too.
For seafood, I also like New England Fish Market, 1419 NE Jensen Beach Blvd also in Jensen Beach, but it gets crowded, so insist on a booth or a table in a corner. They sometimes have a "bug in a box" lobster special. They also sell fresh seafood to cook at home.
First off, you need to get out of Port St. Lucie. Go a couple miles south to Stuart.Conchy Joes is a neat place but the food is on the weak side. Go there for the reggae band after dinner.
New england Fihmarket is surprisingly good, but very casual for the prices. They always have one huge lobster (over 10 lbs) in the tank. The waitress said they usually sell it every day or two.
They have one of the nicest fresh seafood markets I have ever seen anywhere.
Believe it or not, I find very few good seafood restaurants in Florida. The best seafood consistently seems to be Bonefish Grill, and I hate to recomend a chain.
One of our favorite spots is Courtines in Stuart. Always good food and service. They have some very nice fish dishes, a great whole snapper
