S: I recommend the restaurant alimentum at 152 - 154 Hills Road.

U: I want to book a table for 2 people at 19:00 on sunday.

S: Have you made the reservation?

U: No I would like you to make the reservation for me please.

S: I couldn't find an available table for you. Would you like to find another restaurant?

U: I guess that would be fine, I really want modern european food. Could you make sure it is in the same area and price range.

S: Unfortunatly, I can not find anything available given your parameters.

U: I need a place to dine, does not matter what type, in the moderate price range.

S: I was able to book yippee noodle bar, reference number is UCWKFIS4.

U: Do they have really huge portions there?
S: Past patrons at the Yippee Noodle Bar say you are given a lot of food.  Is there anything else I can help you with?
