My niece is coming to London with her parents for her 15th birthday in a few weeks. We would like to take them out as a treat, probably on a Sunday to breakfast/brunch or afternoon tea although lunch is an option too - we want to fit in around some sight-seeing.
We don't see her very often so I'm not too sure of her tastes. We want somewhere a bit special, not too worried about price, and in terms of areas we're pretty much talking anywhere central. Would be great to hear of anywhere that has been a hit with the 15 year olds in your lives!
