We did the Drink London tour with Chris. The tour was about 3.5 hours long and included stops at 5 pubs. I'd say this is really more of a historic walking tour with a drinking component. We learned a lot of interesting facts about "The City" and all of the pubs selected for the tour were unique and had interesting histories.
Overall it was a fun way to spend an afternoon. Drinks are not included in the price of the tour, so guests are on their own. With 5 pub stops, you could potentially get pretty drunk (if you wanted to).
My only suggestion is that I think this tour would run better with 4 stops and kept to 3 hours. By the end we were pretty hungry and the pubs were getting pretty crowded as the office crowd left work had headed out for a pint. read more
