  This is a small room with a front counter blocking access to half of it. 
Behind the counter is a young gnome sorting tokens and keeping track of gold
coins.  On the walls are pictures of Ganuk and his invention, the Iron Worm,
as well as of his son, Ganuk Junior.  There are some steps leading down into
the departure station, and a sign tacked to the front of the counter.  
[Shop] Ganuk Jr. is selling tokens for the Iron Worm.
'Welcome to Ganuk's Express Travels!' Ganuk Jr. exclaims to you. 'If you would like to take a ride in the Iron Worm, just buy a token
of the appropriate city from me and give it to my father, Ganuk, downstairs in the departure station.'
