U: I would like to book a taxi to commute

S: Where would you like the taxi to take you, and when would you like to be picked up?

U: Well I suppose I should choose a restaurant first. Do you know of a seafood restaurant on the west side of town?

U: Which place is located in an area with lots of different things to do?
S: La Margherita is nicely located while Prezzo unfortunately is in a poor area of the city which is a downside.
