I need to find a moderately priced vegetarian restaurant. 
We don't have any moderately priced vegetarian places in town. Would you like to try a different type of food or a different price range?
Unfortunately no, it has to be vegetarian, so i will have to make my own accommodations, thanks.
There are no vegetarian options in the area.
Okay, what about international food?
I have two - both in centre. The varsity Resturant and Bloomsbury. Would you like to book one? 
Make a reservation at Bloomsbury please, for Thursday night. 
What time do you want to dine and how many people in your party?
Please book for 6 people at 17:00 on Thursday. I'd also like the reference number.
Your table was booked. Your reference number is MLK7FV6P.
I'm also looking for a train. It should depart cambridge and go to stansted airport on thursday. Arrive by 17:00.
Would you be interested in TR9427? It arrives at 16:08 and departs at 15:40.
That would be just fine.
How many tickets would you like to book?
I don't need to book, but could you tell me the total travel time, please?
Sure thing.  Travel time is 28 minutes.  Can I help you with anything else?
No, I think that should be all for me today. Thank you so much, you've been very helpful!
You're welcome, have a great day!
