l am looking for a restaurant. The restaurant should serve gastropub food and should be in the center.
Alright, we have three restaurants available. Did you want it to be expensive or moderately priced?
It is a special occasion so I am hoping for an expensive place.
Okay, there's the backstreet bistro and the slug and lettuce. I recommend backstreet bistro. 
What is the address and post code for the one you say is best?
Backstreet bistro is located at 2 Sturton Street City Centre, cb12qa
Thanks so much, I don't need anything more today
You are very welcome, thank you as well. Have a great day, and let me know if you need any more assistance.
