Shad Thames is that street next to Tower Bridge with those iron walkways that you know off Instagram. It can get a bit full of tourists round here, but Watch House is a slick, comfortable spot that attracts locals too. If you’re just stopping in for coffee, you’ll be probably be sitting at the front counter area rather than the large comfortable tables at the back, but the service is snappy and friendly, and the coffee is some of the best in this part of town.
