Really good seafood and sides. We had a whole fried snapper with plantains, salad and coconut rice and great ceviche. Right in Crandon Park. Can’t beat the atmosphere.
FOOD OKAY, BUT RIDICULOUSLY OVERPRICED My wife and I shared a fried shrimp platter here (see photo) while exploring South Crandon Park on Thursday afternoon, February 12, 2026. Everything on the menu was SUPER EXPENSIVE, but looked pretty good. Our platter came out piping hot, and the portion was big enough to satisfy our appetites and it tasted great, but the bill (without drinks) was $36.34. The building also holds a 19th Hole Bar and Grill directly next store, which I assume is operated by the Crandon Park Golf Course across the road. We ordered our drinks from there (19th hole) thinking they'd be less expensive, but just three beers and a diet coke and a bottle of water cost us $47.25. I kind of felt like these two little food shops near the beach, but with no real view of the water, are priced like a food outlet inside of an airport terminal where you have a "captive market" and there is very little competition. This place is just like, that because the nearest other restaurants where alternative and more affordable places to eat are 2 miles south of here in the Key Biscayne village area. I would not recommend eating here unless its on a holiday or a weekend, you forgot to pack a picnic basket, and you don't want to lose your beach parking space.
A perfect lunch on the beach ... fried fish, tostones, coconut rice with a beer from the bar next door. Life doesn't get much better than this!
On New Year’s Day, my wife and I were walking by the beach in Crandon Park, Key Biscayne, and noticed a small restaurant open for breakfast. The service, eggs and salad, atmosphere could not be better to start the year. Highly recommended.
