U: I'm looking for a restaurant in the centre of Cambridge which is pretty cheap in terms of prices.

S: We have many places that meet that criteria, is there a type of food you would like to eat?

U: cheap food is preferred, but i'm not picky.

S: There are 15 places to choose from, what kind of food are you looking for in particular?

U: I don't really care which type of food. You can just pick one and book for 5 people at 12:30 on thursday.

S: I have booked a table for Dojo Noodle Bar for 5 people, reference number 14M7PHJH. The table will be reserved for 15 minutes starting at 12:30.

U: Do you know if it has a nice outdoor place for dining?
S: There is no outdoor dining at the Dojo Noodle Bar, unfortunately. Would you like to change your reservation?
