The "Frog Legs Bernard Loiseau" served at Chef Roland Passot's temple of French cuisine honor both their inspiration the brilliant but tortured chef who committed suicide when it was rumored that his three-star restaurant might be reduced to two stars and Passot, who one trusts approaches the first San Francisco Michelin guide (coming this fall) with a greater sense of equanimity. This dish is one of La Folie's best, at the same time modern and traditional: a ring of plump, juicy, sautéed frogs' legs set around a target of snowy garlic purée and bright-green parsley coulis. It's pretty and delicious, the main ingredient a rare and welcome sight on local menus.
