The absolute minimum for such a service is 1 server per table up to 12 seats. In some cases, additional staff would be required. That is also just for the food. You will need additional wait staff for water, juice, or soda, depending on the level of service (STANDARD VS VIP). There are three methods of serving a sit-down dinner:
1. Family Style
This is where the staff bring large platters of prepared food, and the guests do the, “Please pass the peas,” thing with the various trays.
2. Plated Meal
This is where the kitchen staff prepares the plates in full before service. The wait staff bring the finished plates to the tables. Generally, what’s on the plate is what the guests get, with the exception of bread baskets or similar items. If there is a choice of entrees, the wait staff will take the guests’ orders prior to bringing the meal.
3. French Service
With this kind of service, the wait staff will bring a rolling cart to the table for the guests to inspect. The platters on this table will contain the food to be prepared. If the rolling cart passes muster, the dishes are then prepared and served.
