This is a room in the caverns that is very plain in appearance.  The
lighting is provided by a yellowish globe floating near the ceiling.  You
can hear the sound of something alive (you hope!)  Moving around nearby. 
You also hear some clinking sound, while the wonderful aroma of food
tantalizes your senses.  To the north and south are more rooms with
yellowish light.  
A brownie is getting into mischief here.
