I've been waiting a long time to post a review of my trip to Prague and London, and I've decided that the one thing that stands out in my mind is actually the meal I had before. I went to London last year for Thanksgiving and did a search online for the best coffee in London. One place consistently came up - flat white. So I went once to try it out and ended up going everyday I was in the city for the rest of the trip. I told the gentleman behind the counter when I was there that first day that I would be there everyday after. On or about the fourth day he said, "You weren't lying, were you?" No, I always keep my word.
So when I was back in London for a day on my way out from a week in Prague, I insisted that my travelling companion come with me for a flat white. We had the coffee in the papercup (because it tastes different in the glass) with their halumi bagel. It was exactly like I remembered it.
