UK chocolate

Here's some great chocolate I picked up in London (I love to shop at the duty free shop!).  I love the different varieties and think that Cadbury is the best in the whole world. 

You're probably wondering who has this much time to spend staging and taking pictures of chocolate?  That would be me and I'm not afraid to say it, that is after I finish this mouthful of chocolate.  

London Calling

 B and I are taking sort of a spur of the moment trip to London in two weeks.  Thanks to FlyerTalk, I managed to score some great deals with airfare and hotel (which leaves more of the travel budget devoted to food!)

Though I've technically been to Europe before (if you count the Germany and Amsterdam airports), this will be my first time actually exploring this continent (B's too) and we're super excited!  We're thinking of taking the train to Paris for a day trip as well.  There seems to be so much to do in both cities it's hard to know where to start!

Here's my list so far:

To do in London and Paris

1. Obtain every type of Cadbury chocolate made in the UK
2. Eat my weight in croissants                                              
3. aaaaand that's as far as I got...                                         

 

Obviously I need some help--so... what are your must see, must do, and must eat recommendations for London and Paris?
