Science fiction? What's wrong with the Facebook and Yelp you just mentioned? You don't need a perfect website, right?
The science fiction is bit_logic's requests from up at the top of the thread:
* A way to order and pay online.
* Details on their contactless pickup procedure if I drive there. I want them to bring it to my car, then I can unlock my trunk, and they can place it inside and close it.
My neighborhood bar hasn't updated their Facebook page in years.
