Many users have found it uncomfortable working with Dash and me one of them. If you want to use the classic Gnome menu in unity, you can use this program: ClassicMenu Indicator.
Once installed and launched, ClassicMenu Indicator will be stuck to the AppIndicator area. Unfortunately, you cannot move this menu to another spot on your upper panel, and also items are displayed without icons.
ClassicMenu Indicator is still in its first public release, so next releases will witness more improvements.
