Add this code to the end of the example you found on the Gallery page:

; Add a label for the restaurant.
xy = map -> Forward(-105.1, 40.6)
loc = Convert_Coord(xy[0], xy[1], /Data, /To_Normal)
cgText, loc[0], loc[1]+0.025, 'Prairie Dog Restaurant', /Normal, $
Alignment=0.5, Color='red', Font=0

Cheers,

David
