S: we don't have a concert hall in the east, can I check another area?

U: Let's check for a museum, then

S: There are four museums in the east. Cambridge artworks, Gallery at twelve a high street, and Saint barnabas press gallery are all free.  Cambridge museum of technology is 5 pounds.

U: Please book the Museum of technology for two people, any time after noon. I'll need a reference number too please.

S: I'm unable to book that reservation for you. Is there any other information that I can provide to you?

U: How about helping me find a place to eat, then?

S: Sure thing, what kind of cuisine are you looking for?

U: I'd like crossover food in the expensive range, and located in the same area as the museum.

S: YOu would need to select food then I can look that up.

U: I would like it to be crossover food.

S: I'm sorry, I'm not showing any crossover restaurants in the city.  Is there another type of food I can check on?

U: Sure, let's try Chinese then please. And I'd also like the restaurant to be expensive.

S: There are 9 choices.  What area would you like.

U: I don't care. Can you choose one to recommend for me?

S: I like the Ugly Duckling. It's located in the centre. Would you like me to book that for you?

U: Do you know if it has a good portion of foods?
S: Most customers agree that for the price, you get a large portion size. However other customers have complained that the portion sizes are small, especially for menu items like the dumplings.
