The Junior Parlour (JP) is a general meeting place for Pembroke undergraduates, and the focus of college life. Open meetings and debates are held here, as are the college 'Bops'. Pool and table football can be played, and there are vending machines selling drinks and chocolate.
The Junior Parlour is also the name of the student union at Pembroke. See the Junior Parlour website for more information:

You can go next door to the college bar, or go back outside, either to the orchard or to chimney court.
