Kew Gardens Temperate House

 Let me be clear.  My initial reasoning for going to Kew Gardens was that Carl Sagan visits the same place in the series Cosmos.  If you're curious, it's Part 2, "One Voice in the Cosmic Fugue", about 34 minutes in.

The Best Cheese Toasty.

Upon a recommendation of a forum about London, I set out to try "London's finest cheese toastie". Under a pop-up tent in the middle of Borough Market cheesemakers make raclette and cheese toasties, panini grilled cheese sandwiches with red onions and leeks.  At £5 I was a bit skeptical of this glorified grilled cheese, but I can assure you I got much more than I paid for.
