Where I can Go from the menu bar at the very top of the screen?

Open Finder. The 'Go' option should then appear in the menu bar.

This should not be an issue—

Shift Command G is the short cut for Go to Folder

Command Spacebar will open the spotlight search

Is Finder the frontmost application running (i.e., "Finder" is listed in the menu bar).
