I'm looking for a cheap restaurant that serves portugese food.
I have 2, one in the south and one in the centre of town. Both are cheap and serve portuguese food. 
Could you book a reservation for me? I would like a reservation for 6 people at 14:00 on Wednesday. May I also have the reference number?
I have reserved your table. Your reference number is TRQQXOBM.
Thanks for that, I am also looking for a train that should arrive by 14:15 and should leave on Thursday.
Where are you traveling to and from?
I am traveling from Cambridge to Peterborough.
We have many trains that fit your needs. The latest one you could take would be the TR9792 which would have you arriving at 13:56.
OK, thanks. When does that train depart?
