Every restaurant should have signature dishes. Put on the regular menu your signature dishes and don't deviate. That's what poeple come for. And keep this part reasonably small. They in turn will educate the customers.
Waiters sell what people like.
They want their tip to reflect satisfaction. There are computer programs available where printing a new menu every day is no problem at all. Just don't remove your signature items, once established. That will confuse your guest and they don't know what to expect on a daily basis. That will take a lot of trust that takes a long time to establish.
