Visit any of the two Olive Branch restuarants for a pre or post show meal and you'll enjoy a 10% discount on your total bill when you present your ticket for that night to the waiter before asking for the bill.
You can even arrange to have your starter and main before the show, and have your pudding and coffee after the show. Let the staff know you plan to do this at the time of booking.
Olive Branch Bistros can be found at Broughton and Brunstfield - all of which are all within easy reach of the theatres. Visit the Olive Branch website for more information.
