I had sushi there and it was alright....WAY OVERPRICED (and I live in Orlando and know the prices of sushi in this city, being a sushi lover). But again, if you're on vacation I suppose it's expected. I may have caught it on an off night but really for $14 for my roll it shouldn't have tasted as fishy as it did. I believe that night I got a bowl of soup and the roll and that was my dinner.
You should make a reservation there but if you don't it's not the end of the world. We never make them and eat there often.
If you don't make a reservation and it's a weekend during dinner time expect to have a wait of at least 45 minutes (and this is speaking from my experience, which usually is just a party of two - myself and my boyfriend). OR there's first come, first serve seating in the bar area which is cool if you want sushi - like sitting at a sushi bar. (They do full service of their menu here too.) They also have those high top tables in the bar area that are first come first serve. I don't think I've ever had to wait more than 15 minutes there for a table. Just keep your eyes peeled and be on the hunt!
