I don't disagree with you, and obviously the Winkers being complete winkers doesn't strengthen the concept.
But Raymond has said this at the decision meeting two weeks running, and I can imagine that the profit margin on 29 small plates of party fare is quite healthy.
I can't imagine for the life of me why RB and the others would invest in any of the ideas and people this year. But the shakeout has been fairly merciless of the dull, the dreamers and the flaky - my guess is that those little concept nuggets (IMO only the Winkers and D'Soiree raise a glimmer of interest), are rated more than ...errr being able (and willing) to actually cook.
