First point: Roy's is a chain.
Not a Applebee's-esque chain, but a chain. They offer a large menu with some items that appear at every location and the remainder of the menu is left to Chef to write.
Second point: Decent portion sizes.
The apps were a bit on the skimpy side, but the entree made up for it. You get quite a selection from sushi and nigiri to Hawaiian BBQ or a selection of fresh fish. The prices are a bit high, but nothing like you would pay on the strip.
Third point: Excellent Service. Around but not annoying.
My one pet peeve: just like every other restaurant, they HAD to go and put a raspberry sauce with the chocolate dessert. It's been done. Do something different. Better.
