Bangkok is an ok place and there is certainly plenty of walking to be done. One thing I think you will notice while you are there that is in stark contrast to Vietnam is the fact that while there is a ton of traffic there is almost zero beeping of horns going on. I hate that aspect of Vietnam with the tooting of horns even if no one is around. For many Viets, I think it is just habit at this point and they will use the horn even if it is completely unnecessary for them to do so.

Get over to Lumphini Park if you get a chance to say hello to my giant monitor lizard friends.
