I always have, but finally my wife does after trying this restaurant in Bordeaux. Only moules in buckets cooked seven ways, plus cocktails of course. The classic way, steamed with shallots, white wine, parsley, etc is fine with me, but she liked the one steamed with blue cheese sauce. Sheesh.
Warning: Eat a bucket of mussels and your poop will smell like a salt marsh. Oh well.
