We used
Cook'n With Class about a year and a half ago with Marygott. We took the morning market class - it's geared toward giving the visitor to Paris a taste of the markets. The class visits a series of shops on a particular market street and plans a menu based on what's available. Class size is limited to six. Very highly rated at TripAdvisor - it's the #1 rated "attraction."
