I suggest you prepare a few questions before applying: Why do I want to work in a vegetarian restaurant? Why do you want to work in a vegetarian restaurant? What kind of work am I suitable for? What is my stability and potential? Do I have the cultural quality to work in a vegetarian restaurant?
Running vegetarian restaurants pays more attention to the cultural literacy of employees than running vegetarian restaurants, especially high-end vegetarian restaurants, because vegetarianism belongs to the field of cultural sharing, so you'd better make some preparations.
Finally, I wish you success in your work and happiness.
