Here are some ways to design food delivery app software to accommodate different types of menus and cuisines:
Use a flexible database schema that can store a variety of dish types and attributes.
For example, have fields for: Dish name, Description, Price, Cuisine type (e.g. Indian, Italian, Thai), Dietary restrictions (e.g. vegan, gluten-free), Preparation time, Ingredients, Nutritional information, Photos, Add-on options. This allows restaurants to populate the fields that are relevant for their menu items.
Have a standardized process for restaurants to upload their menus in a CSV or Excel format. This makes it easy for them to provide the required information in a structured way.
Allow for custom fields and attributes that may be unique to certain restaurants. Not all menu items will have the exact same set of data.
Support multiple units of measurement. Restaurants may specify weights in grams, ounces, pounds, etc. The app should be able to handle different units.
Have a standardized taxonomy for cuisine types to properly categorize dishes. But also allow for custom cuisine types if needed.
Provide templates and examples to help restaurants format their menu data properly for upload. This reduces errors and issues.
Have a team that can assist restaurants directly and answer questions about how to provide their menu information for the app.
By designing the software and processes in a flexible yet standardized way, you can accommodate the wide variety of menus, dishes and cuisines offered by different restaurants and food vendors.
