U: I am  traveling to Cambridge and looking forward to try local restaurants.

S: Great! Cambridge has many restaurants! Is there a certain type of food you'd like or a certain price range?

U: Maybe I should figure out my train first.  I am departing from Ely on Friday and want to get to Cambridge by 9:30.

S: The TR8510 leaves at 07:35 and arrives by 07:52. Would you like me to book tickets?

U: Do they allow pets?

S: Yes, you may bring 2 pets as long as they are in a basket 85x60x60cm or a short leash. Would you like to make a reservation?

U: Yes, please. I will need 5 tickets.

S: Okay, your booking was successful. Your reference number is EVDO33LE. 22 GBP is your total and it's payable at the station.

U: Will I be able to change this ticket later if I need to?

S: No, you will need to get a refund. Are you needing any other information about the area?

U: I am also looking for a restaurant in the West and really want to have Brazilian food.

S: that type of food is not served in the west. can we change location?

U: let's change location and the restaurant should be in the expensive price range.

S: It looks like there aren't any expensive Brazilian places in the city.  Would you like me to check a different price range?

U: Can you see if there are any expensive european food?

S: Cambridge Lodge Restaurant will fit your needs. Would you like for me to book a table?

U: Does the restaurant serve alcohol?
S: Yes, the Cambridge Lodge Restaurant does serve alcoholic drinks. They do have some really mixed reviews, though. Half of the customers think the drinks are really good and affordable while the other half thinks the drinks are not very good and overpriced. Would you like me to find another place with better ratings?
