I am looking for a restaurant called the Slug and Lettuce.
I found a listing for the Slug and Lettuce.  The address is 34 - 35 Green Street in the center of town.  It serves gastropub food. 
that sounds great. Could you make a reservation at 16:00 for 2 people this Saturday?
Unfortunately the booking was unsuccessful, would you like to try a different restaurant or different day and time? 
Yes, is there anything else in the same vicinity and the same general price range?
I have Backstreet Bistro and The Cow Pizza Kitchen Bar. They both serve gastropub food. Which one do you prefer?
Nah, either one is fine. I need a reference number though.
Ok, I have booked you at the backstreet bistro. Reference number 42VFS0SM. Is there anything else I can help you with?
That will be all. Thank you for your help!
Okay. Glad I could help.
