Optimize database for multiple restaurants menu

Hi guys, I’m working on a restaurants/listings-type of app where I need to upload a food menu for every listing (restaurant) i make; I need the menu to be organized in categories (dessert, side dishes, pasta dishes etc.) and in every category I need the respective dish (in dessert being ice cream, cake etc.)
I’m looking for the best way to do it since I’m a new bubble user.
Thanks in advance
