Domains: restaurant, hotel

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

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

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

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

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

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

user: How about a Guesthouse in South side instead?

assistant: 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?

user: Sure, what about in the city centre?

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

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

assistant: 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.

user: Okay. Can you try booking the El Shaddai for me fo Saturday for 2 people for 3 nights.

assistant: The booking was successful. Your reference number is S8LZAB9P . Is there anything else I can help with today?

user: No that would be everything, thank you!

assistant: Okay! Glad I could help. Enjoy your stay.

user: Thank you, I will.

assistant: Good bye, thank you.
