U: Im looking for an italian restaurant.  I also need it to be near the center of town.

S: There are 9 italian restaurants in the center of town. Do you have a particular price range in mind?

U: i need a cheap restaurant

S: There is Pizza Hut City Centre, Ask, and Zizzi Cambridge, which would you like to book?

U: Can you book a table for 7 at Ask? We're looking at 14:00 on Saturday.

S: Sorry, there are no tables available at Ask at that time. Would you like to book another day or time, or perhaps another restaurant?

U: Can you try 13:00, then?

S: 13:00 it is. Your table at Ask will be held for 15 minutes, and your reference number is L2KZYL26. Can I help you with anything else?

U: I'm also looking for a hotel

S: We have 33 different hotels.  Did you have a price range or star rating in mind?

U: Something in the cheap price range including free parking

S: What area would you prefer to stay in? This will help narrow down your options.

U: I would like to book a hotel close to our restaurant here in the centre, it will also need to be cheap, and have free parking.

S: There are two hotels available. Would you like me to book one for you?

U: Yes please.  The our group of 7 will all be staying there for 3 nights starting Saturday.

S: I've booked you a 3 day stay at the Alexander Bed and Breakfast for 7 people. Do you need anything else?

U: Are the mattresses good?
S: Yes, the beds at the Alexander Bed and Breakfast are very comfortable. Can I answer any other questions for you?
