Domains: restaurant, train

user: I want to go to a restaurant in the south of Cambridge that serves Spanish food.

assistant: There are no restaurants in the South that serve Spanish food. Would you like me to try another area?

user: Sure, what is the closest restaurant nearby?

assistant: I have one in the centre of town would that be okay?

user: I would prefer it to be in the south and be expensive.

assistant: I am very sorry, but the only Spanish restaurant I can locate is in the centre and has moderate price range. Can I give you more information on it?

user: Can you find me a cheaper place. The type of food doesn't matter.

assistant: The dojo noodle bar may be a good option for you.

user: Sounds good. Can I get the postcode please. Also, I am looking for a train that departs from Cambridge on Thursday.

assistant: The postal code for the Dojo Noodle Bar is cb21rq.

user: The train I need would be departing from cambridge on thursday after 08:30 and arrive to peterborough.

assistant: Train TR4863 leaves at 8:34 and arrives by 9:24, would that work for you?

user: Yes, that would work out just fine. I need to book for 5 and get the reference number too. Thanks for your help!

assistant: Reference number is : IPBCT9UG . Is there anything else?

user: No that is all! Thank you!

assistant: Your very welcome. Have a nice day.

user: You too! I hope you have a great day. Thanks for your help.

assistant: You're welcome, glad I could help.
