Where should I take my sister in Bangkok?

My sister arrived in Bangkok safe and sound on Friday night. We had a great night out dancing to the early hours on Saturday, followed by checking out the new movie “untraceable” yesterday - Good movie by the way!

When you live in Bangkok, you sort of have the same routine, I spend most of my time either at work, in a restaurant, down the pub or at home - It would be nice to break out of this routine while my sister is here. As my sister has already done the touristy things on her previous visit, I’m kind of stuck for ideas as to where I can take her.

Okay, there’s shopping, eating, the spa, more shopping…. And I guess more restaurants to visit. But how about in between, have you got any ideas?
