U: I need to find a place to dine in the expensive price range that serves indian food.

S: Hi, I have several Indian places , what side of town?

U: I think I'd like to eat on the west side.

S: I have five different places that meet this criteria. How does the Tandoori palace sound?

U: That sounds wonderful. Can you book me a table for 7?

S: I'd be happy to reserve your table. What day will you be dining there, and how many in your party?

U: This will be for 7 people at 19:15 on friday

S: I am sorry, but that time slot is not available. Is there another time you would like to reserve?

U: Yes, how about 18:15 on Friday?

S: Booking was successful. The table will be reserved for 15 minutes. Your reference number is B4JDF0YQ. Can I help you with anything else?

U: I would also like to find a guesthouse. I want something 2-star that has free parking and free wifi.

S: Do you have a specific area or price range in mind?

U: Not really. I just need a 2 star guesthouse or 4 star hotel.

S: I don't have any guesthouses that are 2 star. I have 3 hotels that are 4 stars. The Huntingdon Marriott, Cambridge Belfry, and the University Arms Hotel. Which do you prefer?

U: How about a guesthouse with a star of 4?

S: Okay, we have the allenbell that fits your needs. Would you like me to book a room?

U: Could you let me know whether the Allenbell has a good Internet connection?
S: Yes, previous guests that have stayed at the Allenbell appreciated the extremely fast and superb quality of their internet.
