I'm aware that the usage of the sandwich icon and side bar for mobile apps is wide-spread and well known by the users (so it seems, anyway), like this one from the Facebook app:
I'm developing an interface for an web online digital menu for restaurants and I believe this concept might come in handy for navigation purposes.
The only thing I'm afraid of is that this may not be clear enough for web users who aren't using a mobile / tablet.
My question is: is this a good choice or is this probably going to pass unnoticed? Maybe, given the lack of other navigation menus, the users will be curious/persistent enough to find it?
