U: Hello! I'm looking for a cheap restaurant that serves modern global food.

S: I have not located any restaurants that serve modern global food, would you like me to locate a restaurant that serves a different food type?

U: Well, that is disappointing but maybe we could try italian.

S: i got five. any specific area you prefer?

U: Centre of town please. I need to book a table for 7 people at 17:45 on Thuesday.

S: Okay, that narrows your choices to three: Pizza Hut City Center, Ask, and Zizzi Cambridge. Any preference?

U: Can I have the one that offers the best value for their pizza?
S: Zizzi Cambridge has good reviews on the value and prices of their food. The other two seem to be more expensive. Would you like to know more about any of them?
