I like your first set of examples. I keep thinking it would be great if it were integrated with OpenTable. Then you could ask for recommendations for a restaurant with availability for a reservation at a specific time or time range and then reserve it. That would be a killer experience.

I'm not sure though about Siri asking for more information though. Having your phone start asking you questions would be disruptive -- the audio equivalent of a pop-up on a webpage asking you to fill out a survey. The only thing that would make Siri asking you for information unprompted than the pop-up is that it could happen anywhere.
