Fred was our tour guide. He was fabulous. Animated, well versed, very knowledgeable, and everything except boring. AND to top it off, the tour was free. So much better than paying 12 pounds for a one hour tour with an old repetitive professor. We loved the walking tour so much my friends and I wanted to go on the pub crawl later that evening. They were able to squeeze us in with our last minute reservation and we had the best time. Tons of good stories, laughs and delicious ales. I would definitely recommend it.
