A number of major fast food brands have already or are currently looking into rolling out digital menu signage in their premises. Such boards offer flexibility and allow businesses to look extremely modern and extremely attractive. However, they can also remove a great deal of personality from a premises, and whilst they may be perfect in major, ubiquitous fast food chains, they will very rarely work the same way for any other business.
Ordinary menu boards show personal flair and help add a touch off individualism to any premises, even those that happen to be just one part of a much larger chain of cafes or restaurants. Not only do they help give each individual restaurant its own unique sense of style and personality, even within the context of a much larger corporate identity, but they also show effort and creativity, and whether chalkboards are used and filled in by hand or whether unique menus are printed out on a regular basis, the physical will almost always be far more effective than the digital.
There are of course benefits to digital signage but few of them will justify the hefty costs, and the few benefits there are will almost always fail to outweigh the benefits of going for a much more simple and personal option.
Animations may be attention grabbing, but they often lack any true identity, especially in the case of menus. Selling food is all about conjuring up emotions and associations, and giving too much away too soon may actually have a negative effect.
Ultimately, analogue menus will be far more unique and far more interesting than digital signage, and will always look far more impressive and far classier. So unless you have a huge fast food chain to promote and a great deal of money to throw away, simple menus will usually be a far more effective option.
