You call the in-room dining. It's called the 'Ohana Twilight Fest if I remember correctly. 40$ per adult with 18% tip + a 3$ fee for delivery.
I ordered food for 1 (you don't have to order food for the whole family like you do at the restaurant) and I received food for 2 (a whole bread, a huge bowl of salad, etc. In the end, my husband helped but a lot of food went to waste) the only downside is that you don't really get to choose how much you receive from each kind like youwould at the restaurant BUT I managed to get more dumplings by skipping on the shrimps. they are giving you a little bit of everything.
I was not hungry for the bread pudding that night. I kept it in the fridge and we put it a few seconds in the Captain Cooks microwave and I had a delicious breakfast the next morning.
Fun story: after the meal we left the tray outside. We went out for a walk but after we left, someone had actually went through the rest of our food and ate some of it and threw the chicken wing bones on the elevator floor.
