Restaurant websites are usually visited in a hurry, on a phone, with a decision about tonight. Menu, hours, location and booking are the whole job, and design that delays any of them tends to cost bookings.
Restaurant sites are rarely browsed. They are checked — quickly, on a small screen, by someone who is about to decide where to eat.
That makes speed to information the entire conversion problem. A beautiful site that puts the menu two taps away loses to a plain one that puts it on the homepage.
FixSift reads your homepage for exactly that: how many steps stand between arriving and knowing what you serve, when you are open and how to book.
