There are 14 expensive indian restaurants in the city. Do you have a preference of location?
Yes.East-Side London.

Your table for 4 has been booked.  The table will be reserved for 15 minutes.  Your reference number is 8OZ8ZF5G. Do you need anything else?
I am also interested in attractions in the centre.  Specifically, I am interested in multiple sports facilities
