- Runs on a Mac Mini with touchscreen and cash drawer;
Has support for pizza-specific order details, such as, two toppings on one half, three different toppings on the other half;
Understands delivery orders as well as in-person orders;
Can do caller-ID-based database queries, to enable conversations like, "Is this Foo? Are you still at 123 Bar St.? Would you like the same thing you ordered last time?"
There are a huge number of rather sophisticated looking pizza-restaurant-specific software packages out there for Windows that do this and more, but I haven't been able to track down any Mac versions yet.

We inherited a Linux-based POS from the previous owners, but it's crappy, and tech support is from a phone bank in India, so we're just going to junk it.
