I thought the service was quite good. We were dining using a Groupon but were treated like any non-Groupon diner.
First time using Groupon at Roy's. Their offer was a three-course prix fixe dinner, with dessert.
When using Groupon: let your host / hostess know as soon as you walk in that you are using it. They will then know which menu to hand to you.
It helped that we dined early (6:00 p.m.) and it was a Sunday night. Not an overflow crowd.
There are five or six entree choices on the Groupon VIP Partners menu. I had the whitefish, which was very good. My partner had broiled chicken, also good. We shared a choice of two appetizers (spring rolls or makisushi); the sushi felt rather soggy and fell apart once it hit the sauce. Should have gone with the spring rolls. For dessert, we shared a fruit tart, also good.
The server will remind you, as a Groupon user, about the value of the Groupon in order to factor that cost into the overall tip (drinks and taxes are extra).
Was not used to the complementary valet parking, but it worked well. I don't know if there's a self-park option.
One of my better meals at a Roy's. Would certainly return to this one.
