The guest orders
For the person at home, or at the table
One storefront across all four houses. A guest chooses delivery, pickup or a table, and the menu changes to match — the things that cannot travel simply are not offered. The kitchen system prices the order, not the phone: whatever the guest's screen adds up to, the branch's own figure is the one that stands.
Try: add a rib eye, then switch to Pickup — the delivery fee and the service fee both disappear, because a collection carries neither.
