Have not tried Chef's, but Rose and Crown was excellent during our May visit, the only problem was DW kept stealing fron my plate! Rose and Crown was better than the cheese course at V&A a few nights later.
I had the cheese plate appetizer at Chefs de France last August for lunch. I asked if I could have it as my main meal. There was a variety of wonderful French cheeses. They added greens and dressing on the side. It was delicious and beautifully presented. With their good bread, and a glass of wine, it was a great meal (and very low cost- I was just billed the appetizer price).
