I'm looking for a place to dine that serves gastropub food. I want it to be expensive. 
We have 3 options in Cambridge for expensive gastropub food. Would you prefer a place in the centre or in the east?
I'd like to dine in the center of town, please.
I have two in the centre, the Backstreet bistro and The Slug and Lettuce.  Would you like for me to make you a reservation?
Could you give me the address and phone number for the Slug and Lettuce please.
The slug and lettuce is located at 34 - 35 Green Street, postcode cb23ju. I'm sorry our system does not list their phone number. Is there anything else?
I wish you could provide their phone number. But other than that you've given me everything I need to know. Thank you goodbye.
You're quite welcome! Thanks for contacting the Cambridge TownInfo Centre and have a great day!
