Cold, hot or a combination?
A cold selection may include salads, spreads and portioned starters. Adding hot main dishes changes the service requirements: appropriate hot holding, power connections and a defined serving period are needed. Cold food also needs a refrigeration plan; room temperature is not a substitute for suitable food handling.
Plan a meal, not a collection of extras
A starting point could include a lentil-and-vegetable dish, roast chicken, herb potatoes and two contrasting salads. Agree sauces, sides and portion sizes together. Plant-based guests need a substantial combination of their own. Add further dishes only where they contribute something useful to the meal.
Serving routes and replenishment
The buffet needs queuing space and a clear route back to seats. Where possible, separate drinks and used-tableware return from food collection. Discuss smaller replenishment batches, labels and separate serving utensils. A floor plan often helps more than headcount alone.
