title: Builder Vs Decorator pattern
body: <p>From <a href="https://stackoverflow.com/questions/328496/when-would-you-use-the-builder-pattern">When would you use the Builder Pattern?</a>,</p>
  
  <p>It is said that builder pattern is appropriate for Pizza example.</p>
  
  <p>Why not Decorator ?
  by treating Cheese, Pepperoni, Bacon as additional decorations on a base pizza.</p>
  
  <p>Is it for the reason that Cheese/Pepperoni have to be built seperately. I don't think, they need to be built seperately as they can be available readymade.</p>
  
  <p>Pls clarify.
  Am also looking for a good real-world example of decorator pattern and reason why it is the apt for that particular example. Thank you.</p>
