U: I need help finding a restaurant in Cambridge.

S: What type of food do you want? I have asian and african cuisine

U: I would actually like to find something that's serving modern European food, preferably in the centre.

S: I have four options. Do you want cheap, moderate, or expensively priced?

U: moderate please.

S: We have two options - de luca cucina and bar or riverside brasserie.  Would you like me to book a reservation at either one?

U: Which one has the better outdoor dining area?
S: The Riverside Brasserie has a nice outdoor location while that at the De Luca Cucina and Bar has many tables and overlooks a river.
