U: I'm looking for an expensive chinese restaurant in Cambridge.

S: Any particular area you have in mind?

U: I'd like to be where all the action is in the centre of town.

S: I have 4 options that meet the choice of your request though i done have the phone number of one. Do you wish i help you choose one?

U: Yes, please pick one for me.  I need the address with postcode.  I'd also like the phone number too.  Thanks for your help!

S: how about sesame restaurant and bar?

U: Would you happen to know if they offer large potions sizes so I can take home leftovers?
S: The portion sizes at Sesame Restaurant and Bar are really small. Pretty much everyone wishes the portion sizes were bigger, except one person that said the portions were good.
