No, I'm afraid there is no additional menu in Britannia Club. The main features of Britannia Club are the 'Open Dining' times & your own dedicated table for all your meals. Some extra nice features e.g. cheese trolly service and occasionally Flamb'e table side desserts. You can 'within reason' request something providing you give prior notice ( guests in the Britannia restaurant can also make a request from the 'Always available' menu e.g. breast of chicken or minute steak ) .
