Highly recommend. Little scary getting there and from the outside but so glad we went in. Food was amazing. One of the highlights of our vacay. Menu is very large ranging from sushi to prime rib. Tuna tataki is out of this world as well as the scallops wrapped in bacon. Definately check this place out if you can

Just recently returned to the Keys with my girlfriend and I decided to sit at the sushi bar and was greeted by a young man named Connor from Massachusetts. Talked while waiting for drinks and got such a nice vibe from Connor that we decided to allow him to prepare his most enjoyable sushi entrees. We were not disappointed! He... More

Good fresh seafood lunch. Great draft beer selection. Pretty pricey dinner menu. Parking can be tight. Could use a little clean up.

We stopped in for a quick bite and had an amazing meal. The oysters were just wonderful. Crab cakes were full of crab and just enough filling to hold them together. The edamame cooked in sesame oil were oh so good. Everything was great and our waitress was such a peach! To top it off, our waitress brought us a... More

Just average. Got sushi and it was good but nothing spectacular. Friend's hubby got the shrimp Ruben and said it was really good.

driving down to Key West, we stopped about 1 hour before our ETA in Key West. We found it by checking its ratings on Trip Advisor. Yet as we walked up to it, we were unimpressed. Appearances were deceiving! The fish is fresh and delicious. It needed no added sauce. We ate inside but there is a waterside eating area.

Stopped in for lunch and Anna the hostess was the highlight of our stop; Very sweet. Bartender Vicky was slow and offered drinks to a party of four at the bar immediately; after we we had already been sitting and waiting patiently. Had the grouper sandwich... I will say it was nicely blackened but that's the extent of it. Husband... More

We love sushi and decided to give Castaways a try as they had an early special from 3 to 5 with reduced prices on several of their sushi rolls. We ordered 4 of them and they were all very good. We especially liked the orange is the new black. It was more than we could eat and we brought the... More

My wife and I had dinner here based on the ratings it received on this site. We were disappointed with the meal and the service. My wife order the raw oysters as an appetizer and I had the lobster bisque. The oysters tasted off. The manager authorized the waitress to charge us for 6 instead of 12 oysters because my... More
