U: Hello, I am traveling to Cambridge and I'm looking for some local restaurants. I would like to find some located in the Centre and of moderate price.

S: We have a lot of locations to chose from. What type of food would you like?

U: Are there any restaurants that serve bistro food?

S: There are no bistro style places that meet your criteria, would you like another style of food perhaps?

U: how about italian?

S: Sure, there are two such restaurants. How about Pizza Express, at Regent Street City Centre? Would you like to book a table?

U: Yea! Please book a table for 2 people at 15:00 on Thursday.

S: That time is not available, would you like to book another day or time slot?

U: Can you try 14:00?

S: Yes I was able to make you a reservation at the pizza express on thursday at 14:00 for 2 people.  Your reference number is UN9ONONE.

U: I am also looking for a hotel in the same area of the restaurant

S: I have several options. Do you prefer a certain price range so that we can narrow down the options?

U: I don't really care about price range, but I'd like to have free parking.

S: The Gonville Hotel is in the expensive range but is located in the Centre.

U: Is the location a good one for this hotel?
S: Some would consider the Gonville Hotel not to be strategically located, but others thought it was in a convenient location off the highway.
