Cash only businesses. Family, friends all eat there for free, like grandma's kitchen used to be. They gotta eat anyway, and it fills out a restaurant. The busier, the more you pad. Give options of top shelf scotches, etc... A guy is celebrating and wants table service, you provide that. Strip clubs, etc... Easy easy ways to either hide what's coming in, or pad what's coming in. Food trucks are brilliant for this, though stretching the definition of restaurant.
