It would be pretty straightforward to set up a modern-day version of this low-bloat pickup-ordering: - Simple web form with e.g. stripe integration (only paid-for orders are submitted) - Server to process orders and send to restaurant - Local computer and printer (or fax/vfax setup) at the restaurant

Could probably pair with a static CMS for photographs of the food. Delivery is, of course, a whole different problem to tackle.
