As others have mentioned, lunch is an ADR now but it is a quick service credit instead of a table service credit. Yes, you can pre-order your lunch, I think I did ours about 30 days in advance but I believe you can modify it up to pretty close to your ADR date. I do not know when the window officially closes on that. You do not have to pre-order if you don't want to. Pre-ordering is supposed to make things go faster when you arrive, and it certainly did in our case, but I have seen other reports that it did not really work that way, so experiences have varied on that. If you choose to go for dinner, it is a table service credit and you cannot pre-order. For lunch, you can choose to sit anywhere. For dinner, they will seat you. The Beast is there as the dinner host and circulates throughout the restaurant and you can meet him and have pictures with him on your way out. At present, the Beast is not there during lunch. I think the experience is very nice either way, so I would recommend considering whether the use of table service credit/quick service credit is important to you, and whether or not meeting the beast is important, and whether or not you care about choosing your own seat. Of course, the dinner is more upscale in terms of food choices also, while lunch is more casual with mainly a choice of sandwiches although both meals are very good and the lunch, in my opinion, is the best use of a QS credit on property. So the type of food you are hoping for should also factor into your decision. Hope this helps!
