When Austin chef-restaurateur Larry McGuire does a drive-through and walk-up, it’s news. So we queued up. For $14 we got half a medium-sized chicken wrapped up in butcher paper, two sides, tortillas, and salsas. Verdict: Thumbs up for the incredibly moist charcoal-grilled local fowl (ours was seasoned in achiote and citrus). Double thumbs up for the fabulous homemade corn tortillas and the spicy salsas (tomato-serrano and jalapeño-garlic). We also loved the whole jalapeño roasted in soy sauce (shades of South Texas). The Mexican rice with green peas was ordinary (the white jasmine rice is better). But do spring for the utterly addictive Mexican street corn slathered in mayo, cotija cheese, and lime zest. No seating. (6/12)
