The variable menu-bar-mode defaults to t.  In x-create-frame, there are
the following lines:

  x_default_parameter (f, parms, Qmenu_bar_lines,
                       NILP (Vmenu_bar_mode)
                       ? make_number (0) : make_number (1),
                       NULL, NULL, RES_TYPE_NUMBER);

This says that if menu-bar-lines is not supplied as a parameter to
make-frame (or in default-frame-alist), the value of the menu-bar-lines
frame parameter defaults to 0 if menu-bar-mode is nil, and 1 otherwise.
