Online Menu for Restaurant Theme

Hello there,

I’m not quite sure if this is the right place to ask but since you all seem eager to help and support, I’ll give it a try:
I was assigned to build a website for a restaurant.
The webiste should have two main functionalities (A and B):

A - To select / create your own dish (Dish Generator), like:

  1. Step: Select Type of Bread
  2. Step: Select Toppings
  3. Step: Select Sauce

B - Online Order via TakeAway

(C - It would also be nice if you could log-in via facebook or just order as a guest without any login necesssary)

Do you have any suggestions for a theme, which supports both functions or how to build them?

I’m grateful for any help!!

Thanks in advance!

Best regards,
