If you want sushi, then definitely go to Kimonos. It's a sushi bar so the main speciality is sushi. The food is authentic and because the Swan caters to many Japanese customers, the food must be to their standard. It's very good and they're very accomodating.
DH doesn't eat sushi at all, and when we go to Kimonos, they allow him to order from Gulliver's Grill.
Another thing that's fun at Kimonos is that they have karaoke from 9pm every night. If you get one of the couches to sit on, stay for the karaoke cause it's lots of fun to watch (or participate)
