The second coffee shop has to be Kaffeine. Having only recently come across this one, I was certainly impressed and they may even have the best coffee I've had, since a short stay in Portland, Oregon.
Spring always arrives earlier to London, and London shows its most beautiful face during the spring. If you live in London, or if you come to visit, bring your training shoes and take a morning run along river Thames in Chiswick. Between Barnes Bridge and Hammersmith Bridge, there's a great trail on both sides of the river. And if you take the run in March, you might run through this wonderful Alice-in-Wonderland cherry-blossom landscape.
Also the Queens back garden, these beautiful grounds are great for a Sunday stroll to see the pelicans or to feed the squirrels. Duck Island Cottage is worth a look too, a idyllic little cottage situated in the grounds which was specially built as the bird keepers home.
There is a rather beautiful faded glory to these mythical creatures, which flank the steps guarding the ruins of the Italian Terraces in front of the former Crystal Palace, which dramatically burnt down in 1936.
