Arpege
Gluten-free: much of the menu is naturally safe; flag at booking
Arpege is the strongest fit for a coeliac in Paris because Alain Passard built his three-star menu around vegetables from his own gardens, so a large share of the cooking is naturally gluten-free before any adaptation. The kitchen at 84 Rue de Varenne is among the most accommodating in the city for dietary needs. It is not a dedicated gluten-free room, and the famous bread is on the table, but the menu's structure means a gluten-free diner gives up less here than almost anywhere. State coeliac needs clearly when you book.
