Here's one of Richmond's best secrets: every Saturdays and Sundays, on Homebase car park,
there's a French-style market van, complete with the Frenchman selling cheese inside! His name is Michel and apparenly he ferries fresh products every week, directly from France -you can even ask him to bring back any specialy for you.
See the picture as proof.
He sells alls sorts of cheeses, including some real unpasteurised ones such as Camembert de Normandie AOC, Roquefort, Comté, etc... All very reasonably priced, which is even better!
Otherwise, the Real Cheese Company on Hill Rise is good, and so is the special range of Waitrose -just never take the standard Camembert!
Otherwise the Real Cheese Shop in Barnes High street is good and so is the Teddington Cheese shop which has a brand on Hill Rise in Richmond.
