Before we left for Sunday lunch at the Les Deux Garçons restaurant, Aix-en-Provence, I checked the reviews on Tripadvisor. I’m mildly addicted to Tripadvisor restaurant reviews — I enjoy their Pepys-like unselfconsciousness — and never before have I seen opinion so equally divided between praise and censure. According to the dissenters, Les Deux Garçons is ‘a worst nightmare’, ‘absolutely horrible’, ‘a fraud and a scam’, ‘a theatre of clowns’, ‘the perfect place to while away a few hours — if you are on death row’.
