The fish from Lighthouse Seafoods is great. The fish is fresh and local, well, except for the Scottish salmon when that's available. Salmon from Scotland is delicious, my favorite!
You can buy on Thursday through Sunday....from approximately 1pm until 5 or so. If you arrive early, you may be able to buy a key lime pie....they are made by the owner's mother and they are absolutely wonderful!
Lighthouse does have a store in Lake Mary if you want to take a ride....
