Many restaurants have tried this, and end up switching back because comparing prices to other restaurants puts them at a disadvantage. I think the only way for it to happen is regulation that forces it. Might as well include taxes in that price too.
one of the breweries i live by recently moved from non-tipped to tip, and it's generally a disliked change from what I hear because most of the time the brewery is open it's not busy enough to make up for the loss in wages, and then people fight over the really busy shifts.
