Hi saveshambo James advice was only partly right though I'm sure he didn't mean to mislead you. If you are going from east Dulwich to London bridge take the 40 bus ok. Or you can take the 176 & change at the elephant & castle or the 12 & change atthe elephant & castle though it takes longer than the 176. 40 is the best bet as it takes you all the way to London bridge. Good luck Sman!!
