The task is:

Design and implement a REST API without frontend.

Build a voting system for deciding where to have lunch.

• 2 types of users: admin and regular users
• Admin can input a restaurant and it's lunch menu of the day (2-5 items usually, just a dish name and price)
• Menu changes each day (admins do the updates)
• Users can vote on which restaurant they want to have lunch at
• Only one vote counted per user
• If user votes again the same day:
  • If it is before 11:00 we assume that he changed his mind.
  • If it is after 11:00 then it is too late, vote can't be changed
• Each restaurant provides a new menu each day.

• Run: mvn spring-boot:run in root directory.
