U: Hello, I am looking for an expensive Italian restaurant in Cambridge.

S: We have quite a few. May I suggest Frankie and Bennys? They are in the area of Centre at Market Hill City Centre.

U: Great, can you book a table for 8 people at 19:00 on wednesday

S: Booking was successful. The table will be reserved for 15 minutes. Reference number is : OE4QDLK7.

U: Thanks! I am also looking for a guesthouse in Cambridge.

S: There are 24 guesthouses in cambridge, do you have any information to narrow it down?

U: It should be in the same price range as the restaurant, with free wifi and a star of 4.

S: There is no place matching your criteria. Do you want to broaden your search?

U: Yes, please broaden the price search.

S: There are 33 available options in the moderate to cheap price range. Do you have any location preference to narrow down the search?

U: How about any type of hotel in Cambridge, guesthouse or other?

S: How does university arms hotel sound? It is a hotel in town centre, expensive price range & 4 stars. Would you like to book a room?

U: Is the hotel a decent value compared to others?
S: Reviews of the value are mixed, but some guests have felt that it was overpriced. Should I look for a better option for you?
