Idea 1: design around the first visible moment
Dietary table coordination works when meal information stays close enough to seating decisions that service teams can act without second-guessing the room. When the plan starts from how people will read, move, or decide, the rest of the design becomes easier to defend.
Idea 2: make one logic instantly readable
The guest list owner, planner, and catering lead need one interpretation of tags, service timing, and how dietary guests are identified discreetly. That removes the usual drift between the planning file, the printed artifact, and the last instructions given to staff.
Idea 3: simplify what the floor team receives
The final plan should help catering know where special meals go without exposing private details more widely than necessary. It reduces the chance of missed meals, awkward public clarifications, and last-minute seat moves triggered by avoidable service uncertainty.
