Last night we sent our oligarch of offal to spy on Picca's "Mystery Meat Dinner," a procession of Peruvian dishes that incorporated Ricardo Zarate's recipes with tripe, beef lungs, crickets, alpaca, braised intestine, and guess what? Chicken butt! That's right. Starting with a culito de pollo a la brasa, Picca delivered six dishes to the table without revealing their contents, mingling each delicious bite with a mixture of terror and intrigue, before finally revealing what made them tick. Zarate, who plans to open his new Downtown location of Mo-Chica in about two weeks, scored again with a special one-off dinner that we'd like to see join Picca's schedule more often. Take a look at our photos of the night's fare and like the warning on the restaurant's own menu, "best of luck digesting."
