U: I am looking for a restaurant in the centre in the cheap price range

S: We have 15 restaurants that fit that price range. Is there a specific type of food that you are looking for so I can narrow it down a bit more?

U: How about an Indian or Thai place?

S: There are no Thai restaurants. There are three Indian restaurants called Kohinoor, the Gandhi, and mahal of Cambridge. Which one do you prefer?

U: Are there any spanish food restaurants?

S: Yes, there is one called La Raza that fits your requests. Would you like me to book a table for you?

U: Do you know if it has a nice outdoor place for dining?
S: Unfortunately, there's not an outdoor dining area at La Raza. Would you like me to look for an outdoor option elsewhere?
