In the Cartlandia pod right by the Blue Room, Abuelos is devoted to the food of central Mexican state Hidalgo, with rarely seen items like corn smut and the thick-fried decadence of corn-masa tlacoyos. But it makes sense to take the cart at its word and buy some of Grandpa's barbacoa recipe—amid other filling options from carnitas to squash blossom. The slow-cooked pork comes either by the pound for home consumption or in taco form for immediate absorption. It is tender, sweet, spicy and lovely.
