U: I'm planning a trip to Cambridge I am looking for places to go in centre.

S: What type of attraction are you looking for?

U: Anything, really, just trying to kill some time. What's your favorite attraction?

S: There are churches, boats, cinemas, museums and colleges in the city centre.  Would you like information on any of them?

U: Surprise me! Can you send me the postcode of the attraction you choose?

S: You should go see Holy Trinity Church, the stained glass there is simply amazing.  The postcode is cb23nz.  Can I help you with anything more today?

U: Yes - I am also looking for a moderately priced restaurant in the same area.

S: There are 21 different restaurants that match your criteria. Do you have a type of food you prefer?

U: any food will be just fine.Once you find the restaurant you want to book a table for 7 people at 13:30 on friday.
If the booking fails how about 12:30.
Make sure you get the reference number

S: Just to confirm before making a booking: How about Yippee Noodle Bar?  It is in the centre of town and moderately priced.  Would you like this booked?

U: Is the staff friendly?
S: Unfortunately one of the downsides of the Yippee Noodle Bar is that the service is often quite rude and slow.
