We've eaten at Rose & Crown several times in the past month or two, the most recent being this past Thursday.
Things have changed at most WDW restaurants, including Rose & Crown, but R&C hasn't changes as much as some others. The fish and chips is no longer billed as "Harry Ramsden's" and I'm not sure why. It's still good, but not as good as it used to be. It used to come with peas and is now just the fish and chips. The fish is now more 'average' and just a little smaller portion than it used to be.
The prime rib has been gone for years. The soup is still good as is the beer. If you eat outside you may have to share your chips with Brian the squirrel.
