Love the true key feel of the place. Food was good and the service was warm and welcoming. Definitely not fancy but very "keyish".

Amazing food! My hubby had the hogfish with shrimp and scallops and I had the grouper oscar style. Best fish and food we've had all vacation. My son wants to eat there every night till we leave, ha! He enjoyed the sushi. And I can't forget our awesome waitress, Amanda! From small talk to excellent service and even connecting with... More

We sat outside on the water- it is a bit dated, but we thoroughly enjoyed it. Our waitress was great and the food was good. Definitely worth a visit- but sit outside, inside is a bit gloomy.

Everything about this place was great! The service was on pointe, the food was fresh and cooked perfectly, the ambiance is fun and there's a great patio. Not inexpensive but worth every penny!!

Respectable fare but nothing too special. Very friendly people and ample parking out front. But the painkiller has too much coconut milk and the key lime pie was too rich.

This place is a little hard to find, and parking can be difficult when they are busy but it is worth the hassle. This seems to be a locals place, there were a lot of people saying hi to multiple tables when we were there. The food is a bit expensive, but is worth it. The portions are large and... More

This is in a very rough neighborhood, quite scary, actually. But if you are into risking your life for great sushi, then it may be worth it. We had to go back bc the food was fresh and the rolls very interesting!
