I will answer your question in two situations:
1. Any work needs to start from the foundation. Although the above work is not the core of financial work, it is an important part of financial work procedures. Moreover, from your description, the core of financial work is not books and the like, especially if you want to be a financial executive, you must change this concept.
2. Since this restaurant is well-known, generally better enterprises will give employees room for development, so if you do a good job as a financial assistant, you will generally transfer to a financial accounting position. I am such an example, and now I am a financial manager, and the experience I have gained from grass-roots work is very valuable.
when you first come to this industry, don't always think about job-hopping. You should think about learning something. Knowledge is your real wealth, which others can never take away. Only by learning something in a down-to-earth way will your own value be reflected. The changes brought by the embodiment of your value to your life are beautiful, including your family economic situation, personal reputation and so on.
