U: I'm looking for an expensive restaurant that serves gastropub type food.

S: There are 3 restaurants that fit your criteria, Royal Standard, The Slug and Lettuce and Backstreet Bistro. Are you interested in any of these?

U: Are any of these in the east part of town?

S: Yes, the Royal Standard is in the east. I would be happy to book a table for you if you can tell me the day, time, and number of people.

U: I want to book a table for 4 people at 16:00 on friday.

S: I am sorry booking was unsuccessful. Do you have another time slot in mind or possibly a different day perhaps?

U: Is it available at 15:00?

S: Yes, booking for 4 on Friday at 15:00 was successful.  Would you like the reference number for that.

U: Yes please that be great, thanks!

S: The reference number is N91XOAZT. Is there anything else I can assist you with?

U: Yes, I'm looking for a hotel named Limehouse?

S: The Limehouse is a moderately priced guesthouse with a 4 star rating.  Internet and parking are also provided.  Would you like me to book this?

U: Do the rooms in the hotel have a lot of space?
S: No, the rooms at The Limehouse don't seem to be very large. They are described by a past customer as being cramped.
