Fats Food E-commerce website

Hi!

Website: Fast food restaurant which has woocommerce plugin, where customers can order food.

How can i achieve this step by step ordering process:

Step 1: They have to choose between 3 menu’s (small, medium and large).
Step 2: They then have to choose between diffrent burgers and drinks.
Step 3: They can choose between either another menu, which takes them back to step 2, or between single burgers which will be added to the cart and then they can checkout.

Please help!
