Application/Places/System menu in Unity

I have disabled the global menu and want to put the classic Application/Places/System menu in its place. How would I go about doing that in Ubuntu 12.04LTS?

(Note: I do want to try keeping unity as well as the dock launcher around for now to see if I can get used to that)

You could try the Classic Menu Indicator to get an category-sorted application menu in Unity. Another way is to install gnome-session-fallback and to select the GNOME Fallback Mode at login, which makes GNOME 3 to imitate the look and feel of GNOME 2. You could also consider to switch to XFCE, which is quite similiar to GNOME 2.
