Why do some restaurants give you a menu before seating you?
The fastest order is often the one that started earlier.
Customers often think ordering begins when a server arrives. Many restaurants try to start the process earlier.
The hidden mechanism is decision parallelization. While guests wait to be seated, they can simultaneously evaluate options instead of delaying that process until after sitting down.
Imagine a busy restaurant where every table spends an extra five minutes deciding what to order. Those minutes accumulate across dozens of tables and eventually affect kitchen timing, waiting lists, and turnover.
A second-order effect develops because earlier decisions reduce uncertainty throughout the system. Servers, kitchens, and waiting guests all benefit from smoother demand flow.
People often think menus communicate choices. Restaurants often use menus to move decisions through time.
