I went to the one in Woodland Hills, which as I found out when making a reservation, is very popular.
I was a little leery due to the word "fusion" in the title and also because it is a chain (I haven't been to any of the other Roy's). I was expecting a P.F. Chang-type experience.
Both my wife and I were very impressed with the service and the food. It's definitely on the pricey side but I don't mind paying the price if everything comes together in regards to atmosphere, service and the quality (and presentation) of the food.
Few things annoy me more than a high end restaurant with 10,000 wines and offers nothing but American macro lager on the beer list (if you can call it that). Roy's had a good (though not great) beer list. If memory serves correct they had a range of craft lagers and pale ales but lacked stouts (other than Guinness), porters, IPA's or Belgians. Some selections from So. Ca. breweries would make a huge difference in my mind. I had a red ale made specifically for Roy's, the bartender didn't know the brewery of origin but it was very good.
The food was imaginative and well prepared all the way through (starters, entree, dessert). Price-wise it's a special occasion place for us but we'll go back.
On my 1-10 rating scale Roy's comes through with a solid 8.
