A few Raiders and Feral Ghouls.

Notable loot
Узел Метрополитена EDIT: If the book is NOT on the table, look at the very bottom of the rubble, at the floor. I stressed about not finding the book and eventually found it there.
 * Grognak the Barbarian on a table sitting on some rubble to the east of the hallway leading to the Vernon Square North exit. Height-wise, it's halfway down to the platform; a board leads over the railing from the upper level, and there is a table with a lamp on it.
