On 25.3 it seems to be working as advertised.

"
(menu-bar-mode &optional ARG)

Toggle display of a menu bar on each frame (Menu Bar mode).
With a prefix argument ARG, enable Menu Bar mode if ARG is
positive, and disable it otherwise.  If called from Lisp, enable
Menu Bar mode if ARG is omitted or nil.

You can turn it off with menubar > options > show/hide and then on by 
evaluating (menu-bar-mode [nil])
or
M-x menu-bar-mode

(menu-bar-mode 0) evaluated turns it off because 0 is not positive.
