Hi, Matthew, and welcome back to the Disney Parks Moms Panel.
The
Rose & Crown Dining Room has recently become one of my family's favorite spots at
Epcot. My husband and I honeymooned in London, so that part of the World Showcase is near and dear to my heart.
When we were there last month, the large party seated next to us ordered drinks from the
Rose & Crown Pub to go with their meals in the Dining Room, so I would think it wouldn't be a problem to order any item from the Pub's menu. Most of the selections on that menu, though, are also on the
Rose & Crown Dining Room's menu, too. The biggest differences I see are the sides (with English Chips and House-made Seasoned Crisps offered only in the Pub) and the British Butty (also only offered in the Pub). Since both the Pub and the Dining Room share the same space (with only a small swinging gate separating the two) and the same kitchen, ordering from the Pub shouldn't be an issue for you.
I would recommend double-checking with the attendant when you check in for your reservation just to make sure you'll be able to get what you have your heart set on. Since reservations aren't required in the Pub, you can always pop over to that side of the restaurant and pick up an appetizer and/ or drink while you wait for your Dining Room table to become available.
Enjoy your visit, Matthew, and please let us know if there are any other questions we can answer for you!
