user: Can you find me a guesthouse with a 4 star rating?

assistant: I have a number of guesthouses available, do you have a location preference?

user: Not really, but I do need free parking in expensive range

assistant: I'm sorry, but we don't have anything that meets your requests. Would you like to change what you're looking for? Maybe I could help you with something else?

user: what about the one with a cheap range?

assistant: I have seven cheap 4 star guesthouses with free parking in the cheap range. One in the center, three in the east and one each in the north, south and west.

user: Can you recommend one? I need a reservation for tuesday

assistant: alexander bed and breakfast would suit your needs. How many people will be staying and for how many days?

user: i want to book it for 1 people and 3 nights starting from tuesday.

assistant: Reference number is : BL0Z1OXC . Anything else I can help with?

user: I also would like to find a chinese restaurant in the centre.

assistant: What's your price range? I recommend the Ugly Duckling, but it's expensive. Charlie Chan is a good, cheap place, and Lan Hong House is in the middle, price-wise.

user: Let's go with the cheap place. It will be the same day, same people, and we'd like to dine at 14:15.

assistant: Booking was successful and your table will be reserved for 15 minutes. The reference number is DJAKWB3Y . Is there anything else I can help you with?

user: That's all, I'm gonna need. Thanks.
