U: I need a place to stay, ideally it should be 3 stars and moderately priced.

S: Sure, there are some nice guesthouses to choose from.  Would you like to stay in the north, south, or west of town?

U: Centre, please! Thanks!

S: Unfortunately there aren't any hotels available in the area that are moderately priced.  Would you like me to look in a different area?

U: Ok that's fine, let's try something in the west then please, I really need a room

S: There is Hobsons House located in the West that meets your needs. Would you like to book a room now?

U: Yes. That sounds good. Can you book it for 1 person and 2 nights starting from monday?

S: It is not open then, maybe a shorter stay?

U: Okay, try just 1 night instead.

S: I booked your room for 1 night.  Your reference number is IR6YZXFD.  Can I help with anything else today?

U: I am also looking for a restaurant, maybe with english food?

S: There is no restaurant serving english food. Anything else?

U: Could you try again, English food, moderate priced in the centre of town.

S: I'm sorry, but there are no restaurants serving English food in the city. Would you like to try another cuisine? Maybe British?

U: Yes, can you list some that serve Indian food?

S: There are 22 Indian restaurants do you have a price range and area you prefer?

U: I'd like it in the same price range and area as the hotel, please.

S: There is the Meghna restaurant that fits your criteria.

U: Need an place with the wait staff
S: Yes, Meghna is a restaurant, which means that it does have waiters and waitresses to take your order and serve food.
