Bovril,
It was fine for us, Howie gave us an unwanted CRT reservation, it was in his name + the reservation number, table for 5. DH was really sceptical, and the children wheedled the "surprise" out of me, DH was convinced we wouldn't get in, as his name must be banded around every day!! I nearly made a backup for Crystal Palace, but didn't.
We got there 5 mins before, and in we went!! No problems, but we had to wait in the "waiting room" wiith Fairy Godmother and Cruella, my that was a scrum!! Beware, hoardes of American children being dressed up in all their finery, I think our attire would be considered "dressing down" in comparrison!!
Enjoy your breakfast!!
