Hi Danelle!
The
British Revolution performs in the Gazebo located in the beautiful "maze garden" which is located toward the back side of the United Kingdom pavilion in World Showcase of EPCOT.
There is a restaurant close by called
The Rose & Crown Pub & Dining Room, which has an outdoor patio. You may not have a very good view of the band, but should be able to hear it fairly well from this patio.
You are also welcome to order your food from the Quick Service Restaurant called the Yorkshire County Fish Shop. They serve great fish & chips, along with refreshing beverages, including Bass Ale. You can take it with you to the gardens to eat during the performance, though seating, other than a curb, might be difficult to find.
And yes, The
House of Blues Restaurant is located in Downtown Disney West Side, and I can attest to the incredible Sunday Gospel Brunch that serves of some yummy food at an all you can eat buffet brunch, and a dose of Gospel goodness on the side!
I hope you get to enjoy these wonderful, magical Disney opportunities to hear some of your favorite music, and enjoy some delicious eats at the same time!
