U: I want to find a brazilian restaurant that is cheap.

S: I'm very sorry, there are no results for cheap Brazilian restaurants. Would you like to try for a different type of cuisine?

U: Do you have any restaurants in the centre?

S: I have 5 different cheap restaurants in the centre. Three are chinese restaurants, and the other two serve asian oriental. Do you have a preference?

U: How about a Italian restaurant located in the centre

S: There are three in that area. Pizza Hut City Centre, Ask, and Zizzi Cambridge. Is there any more information you'd like about any of them?

U: No, which one would you recommend?

S: I've heard that Ask is one of the best in town. Can I reserve you a table there?

U: Book a table for 1 on friday at 19:45 please. I'll need to have the reference number.

S: Your reference number is JDBOODV3.

U: Excellent. I'm also looking for the allenbell hotel. Do they have free parking and what type of hotel are they?

S: They are a guesthouse hotel with parking. Want to book?

U: What extras does the hotel have?
S: For $510 a night, there is a king size bed, desk, table, and balcony overlooking a lovely view. Would you like to know anything else?
