I would pick lunch. Dinner is so expensive. The soups and desserts, except for the Grey Stuff dessert, are identical at both meals yet they charge more for dinner. At lunch you also have a much better chance at sitting in whatever room you like, and all three rooms are open. I also feel like you are more welcome to walk around and explore the other rooms during lunch. You still get the experience of a waiter bringing you food in the rolling carts; its just all at once instead of offering you dessert. That being said, the butter they offer with the bread at dinner is the best we have ever had.
