I'm looking for a particular hotel called "rosa's bed and breakfast". I've located Rosa's Bed and breakfast, would you like me to assist you with booking a room? Yes, please. I would like to book a room for 3 people for 2 nights, starting from Sunday. I have made your reservation. The reservation number is BNNZYCCS . Can I help you with anything else? Yes, I am looking for molecular gastronomy restaurant located in the Centre that is expensive. I am sorry. We don't have any expensive molecular gastronomy restaurants in city centre. Would you be interested in a gastropub instead? Actually, how about Chinese? We have 4 great places. I'm partial to the Ugly Duckling, myself. Would you like to book a table? Sounds great. I need that for 3 people on Sunday at 13:30 please. Would you like me to make the reservation for you? Yes, please! I'm sorry, I am unable to book the table for that time. Is there another time, or restaurant you would like me to try? Oh, that's a shame. Okay, can you try the same time on Friday instead, please? second time is a charm, you are booked for friday, the reference number is YJR4PW5V, any other questions?
