Sure, you could eat next to water. Or, you could eat on it. Not off a plate on a lilo, but on a canal boat. The London Shell Co is like meals on wheels, but with no wheels and a lot more oysters. This canal boat serves a set seafood cruising menu (if you want to be on the move) or a la carte (if you prefer to be stationary). Though it reads slightly novelty, this is a genuinely lovely experience. Particularly in the evening, where it feels like a romantic and very British mixture of Titanic and The Talented Mr Ripley. Only with far fewer fatalities. Touch wood.
