U: I need to book a hotel.  I need it to be in the town center, and have a minimum star rating of 4.

S: Would you prefer a guesthouse or a hotel proper?

U: It should be a hotel type with free parking.

S: I have found University Arms Hotel on regent street with a 4 star rating and free parking and internet. Would you like to book?

U: Yes, please book that one. It will need to be for 3 people, and we'll be staying for 5 nights, beginning on Sunday.

S: I'm sorry, the booking was unsuccessful.  Would you like to try to stay for a short period or start on a different day?

U: Alright, what about only for 3 nights then. I can do 3, book it and give me the reference number please.

S: Booking was successful. Reference number is : D09887CW. Is there anything else I can do for you today?

U: I'd like to find a korean restaurant in the same area as that hotel.

S: There's a restaurant called Little Seoul.  It's expensive, but also on Regent Street. Would that work?

U: Do you know if there are many kinds of beer available at Little Seoul?
S: I'm not sure, one reviewer said that they had a good selection, and another said they had a limited selection. They also mentioned that the prices were too high.
