Catering for 100 People

The buffet rule for big rooms is one line per 75 people, and the calculator shows why. At 75 guests a single line takes about 23 minutes to serve everyone from one side. At 76 the order splits into two lines, and the wait drops to about 12 minutes. The food barely changes. The serving time halves.

So catering for 100 people has two workable shapes: boxed meals, or a buffet split into two stations. One long table for 100 is the plan to drop. From one side it would take about half an hour, and lunch turns into a queue.

A hundred boxes is a sorting job. With spares the order is 105 to 110 meals, and the first decision is how they reach the right hands. Ask for a name or a diet on each lid. Then lay the table in sections, with the vegan, gluten-free and allergy meals together at one end, apart from the standard ones. Standard boxes go out fast from the middle. Named boxes go out by name, so nobody takes the last gluten-free meal by accident.

Keep the spares behind the table, not on it, and put them out once the named boxes are gone. A latecomer with a restriction still finds a meal. Boxed meal catering packs each restriction as its own meal.

For a buffet at this size, build two identical stations in different corners, not one long table. Every dish appears at both, so neither line has a reason to grow longer. Split the pans the table above lists evenly between the two, and give any odd pan to the station the room reaches first.

At 150 people, the same two stations carry about 23 minutes of line each, the wait one table gave at 75. Serve both sides of each station at that size and the wait falls to about 12. The buffet catering guide covers the order of pans along each line.

Most lunch orders this size are not last-minute. The typical Zerocater lunch order for 75 to 150 people went in eight days before the meal, and more than half were placed a week or more ahead. Labeled boxes need the name list, so the order date follows the day the list is final.
