Sous Chef

Shares a lot of the same responsibilities as the head chef, however they are much more involved in the day-to-day operations in the kitchen. The sous chef also fills in for the head chef when they are not present. They are the go-between the head chef and the junior and station chefs and closely monitor and manage the workings in the kitchen.
Monitor food preparation methods, portion sizes, and garnishing and presentation of food to ensure that food is prepared and presented in an acceptable manner.
