"Can see the departure boards from in here- better than waiting on the concourse"
"Pond on the west side is lovely, very peaceful"
"Usually a short change at SP/Farringdon if you want Herne Hill/Sutton train and only Sevenoaks going after 18:30"
"1.15k on the outmost route if you don't mind running laps. Not much else to recommend it, but grateful it's there"
"A less-polluted alternative to Edgware Road- turn off at Homebase, cut through park, up Colindeep and turn off down Sheaveshill and the park for Colindale tube."
