If you go to eat in a restaurant in London, surely they will ask you something very quickly that you may not get very well when you ask for water. Normally, what they are asking you is “Still or Sparkling?” To order natural mineral water you must use the term “Still Water” since “Sparkling water” is sparkling water. Also make sure that it is what it says in the bottle if you buy water in a store or cafeteria, if not, you will find yourself with a surprise!!
