My past experiences with restaurants on St Barth whose chef (or whoever designed the menu but isn't really there) has a Michelin-starred restaurant somewhere else have been, um, less than stellar. I look forward to trying the restaurants at Le Barthélemy and judging them on their own merits.
The website now reads "Dishes created by awarded French Chef Guy Martin...". I don't expect to find Chef Guy Martin in the kitchen at Le Barthélemy, except perhaps during the Gourmet Festival, just as I do not expect to find Chef Jean-Georges Vongerichten in the kitchen at ER.
