I'm looking for a restaurant the serves spanish food.
Would you prefer cheap or moderate price range?
I have no preference. 
Two selections fit your requirements. La Tasca and La Raza are both located in the centre part of town. Do either of those interest you?
Yes, I would like the address of La Raza please. 
La Raza's address is 4 - 6 Rose Crescent.  Is there anything else I can do for you?
No. Thank you, goodbye.
