The green, donkey-painted festival truck now has a storefront on Chestnut Street in West Philly. Beef birria tacos come three to an order, cheese melted onto doubled corn tortillas, with consomme for dunking and arbol salsa on the side, while the al pastor, pork or chicken, gets shaved straight off the trompo. You order at the counter, and a small dining room means you can eat right there instead of carrying the consomme home.
