Overall: for a chain in this price range I like others better but Roy's does a pretty good job.
Food: quality is what you'd expect from a higher-end chain. Flavor varies greatly. Some dishes are great and others are no better than a fast food Chinese place nearest 'anywhere America' - yes really.
Service: Always very good, never a complaint here expect when they did nothing when my dish was crappy. Did not comp the dish or even offer a desert... no, I did not even finish it.
When to Go: business dinners are the only time I use this place. If I spend my on cash, I go other places and get better food for the same $.
