U: I am going to Cambridge and need a place to eat that serves lebanese food and is cheaply priced.

S: Unfortunately there are no Lebanese restaurants in the cheap price range. Would you like another cuisine type or price range?

U: What kind of cheap restaurants are there in the center of town?

S: I'm sorry, there are none. Would you like to change your cuisine type or location?

U: how about one that serves indian food?

S: I found three cheap indian restaurants in the centre.  Would you like to book at Mahal of Cambridge?

U: Does it have great service?
S: The Mahal of Cambridge has fast, great service. Is there anything else you'd like to know about them?
