There is a extremely comfortable auditorium, with calming beige decor. It has tiered seating with a range of padding, coverage and styles suited to a wide range of possible sophonts.
At the front there is a similarly comfortable setup for a speaker, elevated somewhat and also recorded by hidden cameras and microphones that provide a visual display on screens both above the speaker (to each side of a large projector screen) and on small screens at some of the chairs, and a headphone feed for those who prefer that.
Water glasses are provided and refilled by attentive wait staff, who are also responsible for finding good seats for people and when not needed appear to be enjoying the people watching opportunities.
Suitable buffets with generally non disruptive guests of all varieties have been featuring advertisements for a talk on comparative financial infrastructures, values and systems with the opportunity to ask questions. Each seat is equipped with its own microphone and talk button for facilitating this.
