It's amazing to see London's evolution from a tea to coffee. I'm sure Londoners are still heavy tea drinkers but the coffee culture has slowly taken it over. My last two trips to London coffee shops were all chains for the most part. It's how I fell in love with Caffe Nero. Now you find local coffee shops almost everywhere. It's so cool because now they are starting to roast their own coffee. I have been so lucky to try a lot of coffee shops here. Some good and some bad. However along the way, I have to say that I really enjoyed all of the unique and funny coffee signs that were out. You gotta love British humor.
