Gauron's set up a conference room in the sensoriums to discuss
his plans for the city; true to his word, there is food - pastries, sushi, yakitori, and baozi, for the moment, but it's the sensoriums: it's not like you can't have something else if you want - and several choices of teas and gourmet coffees. One wall is taken up by a massive window, looking out over a partly cloud-shrouded mountainside, but the real focal point of the room is the massive table in the center - more specifically, the three-dimensional map of the city occupying most of its surface, updated to reflect the changes Aang had made to numerous buildings' state of existence.
All that's left is seeing whether anyone actually shows, or whether he'd have to mention that he wanted to pay people for their involvement in this as soon as there was someone in charge of the ship's finances before anyone would be arsed - and probably piss off the command staff in the process, because he hadn't said anything about it to them yet.
