Take the underground MRT to Klong Toei station. Leave by Exit-1 and do a U-turn as you leave the station. With the setting sun behind you, walk down the road and you will pass a yard full of big orange trucks. Continue on, and soon you will come to a 7-11. 

Meet at the soi right alongside this 7-11.

Note this is a slightly different meeting place from last time we ran from Klong Toei.
