So sorry I missed responding to this, but yes you usually seat yourself in the Nomad Lounge. And even though someone else responded I will add on and say that as far as the Nomad Lounge goes, it is a MUST DO for us any time we are in DAK now. Seating in the lounge is both inside and outside and we have always sat on the deck that looks towards the bridge that leads into Pandora. The lounge itself is circular on the inside and I think that it provides an excellent space for people to sit in small groups, relax, and be able to steal some time away from a busy theme park. Joe Rohde designed it with the thought of travelers and people that like to explore the world. It has questions hanging up around it that are supposed to help generate conversation. The outside deck is great, with nice big comfy sofas and chairs. The small plates selection in the Nomad Lounge has delicious choices on it - we used it as our lunch for the day on one trip. And - even though I do not drink - it has been reported on numerous occasions that the leather-bound drink menu is one of the largest and most original anywhere in WDW. I highly recommend the Nomad Lounge.
And don't even get me started on Tiffins. Hands down it is for me the best signature dining experience on property.
