I am planning a trip in Cambridge
Great! Can I help you with transportation, lodging or attractions while here?
I am looking for an attraction called cambridge university botanic gardens. 
That is located in the centre. The address is bateman street. Can I give you any other information?
Can I have their postcode and phone please? Also I need a train out of cambridge on tuesday.
Okay the post code is cb21jf and phone number is 01223336265. 
I need a train that leaves on Tuesday after 9:30 and arrives in London Liverpool street. 
What time would you like to arrive by?
I don't need to arrive at a specific time, as long as the train leaves after 9:30. 
The TR4494 meets your criteria. Would you like to book tickets?
Great can I get 6 tickets for that?
Booking was successful, the total fee is 99.6 GBP payable at the station .
Reference number is : PAR7KYOS.
Great, thanks, that's everything I need.
You're welcome, have a great day!
