Hello! I am looking to have two caterers! I love pizza and my FH loves tacos we will be having someone private do the taco bar and our favorite pizza place do pizzas (each are okay with the other being there). We are thinking about having 150 people the question is how do you know how much food to serve? If you tell each 150 ppl that’s 300 ppl worth of food. Has anyone done this similar situation? Any advice? Thanks in advance!
