Burger assembling may resist, but I know of at least two burger chains that use conveyor charbroilers where you put the patties in on one end and they come out nicely cooked on the other. I don't think those have a large capital cost either.

McDonald's is always inovating on labor reduction. They've got robots pouring drinks now, but they also used to have the size buttons to dispense a specific amount of soda which reduced labor. When you add up enough savings, you can run the restaurant with one less person; which is handy.
