My menus are hidden too. However,  if I need them for some reasons there is some key mouse combo.
Can't remember exactly. Shift right click or C- right click.. something along this.  The menu will pop up as a context menu close to the mouse cursor  location. Be aware there is a customization menu too.

Just in case you look for a quick way to use the menu.

I've had (setq menu-bar-mode nil) in my .emacs for years now and forget
that Emacs even has support for menus.  I don't know anything about how
Emacs implements menus, but if anyone is interested in taking on this
development I'm very happy to consult in the development of and to apply
contributed patches which add Babel menu support.
