Tacos are one of those foods best enjoyed outdoors — yes, even on a sweltering day. It's the Houston way. That's why the all-outdoors Karanchos is such a destination for taco hounds. That, and the rotating pork-on-a-spit called trompo, which marinates in pineapple juice while it cooks. Like barbecue, trompo is best cooked outside. And as with good barbecue, people flock to good trompo from miles away. Get yours on fresh corn tortillas topped with cilantro, onions and some of Karanchos' screamingly hot salsa verde while you belly up to a picnic table in the shade. It's like inviting yourself to a family picnic, only better — you don't have to make small talk with your relatives, just stuff your face with tacos and Topo Chico.
