Transparent Restaurant Backend

In this task, you're going to implement a REST API for a interacting with a menu of a restaurant. The menu is given to you as a JSON file which you will parse and perform operations on. The required features will be listed below.

Description

In this restaurant, honesty is extremely promoted. So extreme, that the restaurant declares that differing quality of ingredients are used in their meals. Like that's not enough, it also allows the customers to choose the ingredients of each meal in different qualities. Each ingredient has the following quality levels:

low: the cheapest
medium: moderate

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).
