U: I'm looking for a place called maharajah tandoori restaurant. Do you know it? It's a restaurant.

S: Yes, it's a luxurious place on the west side. Would you like the number, or a reservation?

U: Yes, I would like to make a reservation for 6 people at 19:30 this Saturday. Could I also get the reference number?

S: Yes! Your all set confirmation number is QX0059LN, anything else today?

U: I was hoping to find a hotel that is 4 star.

S: What part of town are you looking at staying in?

U: I don't care, just as long as it's in the moderate price range.

S: You have 11 options. They are all guesthouses. Would you like free parking or internet at your location?

U: Oh, I really prefer a hotel.  Maybe you could find someplace that is cheap instead?

S: the cambridge belfry is in the west. It's a cheap 4 star hotel. Are you interested in booking a night?

U: Before that, can you tell me if it has clean bathrooms?
S: The reviewer who addressed cleanliness at The Cambridge Belfry was uncomfortable with the lack of cleanliness in the room and bathroom. Would you like me to check one of the other options for you?
