Stonehouse Restaurants (Was Crown Carvery).
Awesome value for money! Just been to the Stonehouse Restaurant The Gap Inn near Notts where you get 2 for 1 carvery meals which includes the large plate options as well. On top of that you can stack 10% off with Defence and Blue Light Card schemes.
Two standard carveries for £5.49
Two large carveries for £6.99
With discount mentioned above it was £6.29 for two large carveries for me!
