Oh dear.

Parisian Chef Nicolas Ronan and Bisou Bistronomy, that little French place in the Castro on Market Street, are now offering something delicious or downright horrifying, depending on your culinary taste: The Escargot Burger.

The burger patty — which, again, is made of cooked land snails — is placed atop a mini sesame seed bun and laced with parsley aioli, coleslaw, tomato, caramelized shallots, and smoked xérès (a sauce made from a demi-glaze flavored with wine or sherry). And in case you're not already feeling French enough, there's an option to add a slice of seared foie gras to the thing.

While I'm down with eating a myriad of oddities — whipped lard, alligator meat, Geno's Pizza Rolls — I think I'll have to take a pass on this latest burger concoction.  Should you want to sink your teeth into a patty of seasoned snails, head to Bisou Bistronomy, 2367 Market (at 17th Street).
