I am traveling to Cambridge and looking forward to try local restaurants.
There are some great ones.  Can I help you find something in particular?
I would like to try some Indian food.
I have 22 restaurants serving indian food. What is your price range?
Any of them will be fine. I'll just need to know the price range, address, and postcode, please?
Okay. The Curry Garden is located at 106 Regent Street City Centre. The postcode is cb21dp and the price range is expensive. 
am also looking for a train. The train should leave after 21:15 and should go to cambridge.
The train should depart from stansted airport and should leave on saturday
Do you have a time that you could like to arrive by?
No, I just need 6 tickets departing after 21:15.
