King’s Cross side exit
King’s Cross is a bad place to meet an escort and a good place to leave from. The side exit you mean has to be named, because the main hall is a city of its own.
A flat near the station is still a street and a buzzer. The station clock does not help once you are on the wrong side of the tracks.
The other London notes are Shoreditch after ten and Notting Hill after the market.
