We called the room service number and asked if we could order food from the Narcoossee menu. The menu was not in the room. The first night I looked at allears menu, but it was a little out of date, so the second time we ordered we checked out the menu posted outside of the reastaurant before we ordered.
I am not sure if only GF does this or if it could be done at any deluxe. I had read about it in the GF thread on the resort board. It was great, the Narcoossee menu was much better than the regular room service menu.
