We went to Roy's earlier this week. My wife and I have been to Roy's many times on the Islands. I've also been to several in the USA but we had the in-laws in town for the holidays and brought them here.
All of our meals were really great. Obviously not as fresh as on the Islands but definitely it was great. We were at the Roy's on Kauai a few months ago and really enjoyed our meal.
This location has an island feel to it. Our in-laws all really loved their dishes. The food was cooked to perfection and the service was great. Our water glasses and ice tea glasses were never empty.
As others mentioned, it's a bit on the price side. It's easy to spend money here if you're getting appetizers, drinks, main course and of course the dessert (get the molten lava cake!). But definitely the food is great and the service is great as well which is expected when you spend this kind of money.
