Dealing with clients during the private chef meal

Once the guests have arrived, it will be important to create a friendly and professional atmosphere. Upon arrival of the guests, it is important to introduce yourself and before serving, talk a little about your background and the dishes. You will serve the dishes.

What should I do once I have prepared the dishes ?

Much depends on the client. When you get there, ask them what kind of service they are looking for: a professional and discreet Chef, or a friendly and sharing experience. In each case, you have to adapt.
The most important thing is to have finished your work, performed the service and clean up. Following this, feel free to interact with customers if it is suitable.  Finally, when everything is over, go have some rest!
