U: I need a restaurant to dine at in Cambridge on my upcoming trip.

S: There are lots to choose from. What type of cuisine are you looking for?

U: I don't care. It needs to be on the south side and moderately priced.

S: There are 2 options, pizza hut cherry hinton which serves italian and restaurant alimentum which serves modern european.  Can I book you for those?

U: Yes please.  I also need a hotel with at least 3 stars and free parking.

S: There is no hotel in south side,do you want me to try different area?

U: How about a Guesthouse in South side instead?

S: I'm sorry, there is no guest house that meets those criteria, either. Would you like to try a different rating, or a different area?

U: Sure, what about in the city centre?

S: I am not finding a guesthouse that meets your criteria.  Might a hotel work?

U: Is there not one in the same area as the restaurant?

S: There are 2, the Alexander Bed and Breakfast 4 star or the El Shaddai 0 star.  Both are in the cheap range and in the Centre.

U: Which one has higher ratings for customer service?
S: They both have a really great reviews when it comes to their staff. I don't think it will matter which one you booked. You will get a good experience.
