Haley's Pick 🍽️

You probably know her as @milehighandhungry. Each week, Haley shares the one place she’s obsessed with right now. From hidden gems to hot new openings, if she picks it, it’s worth the hype.

Haley's Review of Riot BBQ
Riot BBQ on South Delaware feels like a backyard cookout run by a Top Chef, because it is. Chef Manny Barella and pitmaster Patrick Klaiber have teamed up to blend Monterrey flavors with Texas-style smoke, and the results are seriously craveable.

The brisket steals the show: tender, deeply smoky, and finished with Barella’s bold spice rub. Get it solo or wrapped in buttery Raquelita tortillas. The pulled pork brings heat with ancho, guajillo, and morita chiles, and the al pastor ribs are sticky, sweet, and slightly charred in all the right ways.

Even the sides are insanely good! Think crunchy pepita-macha slaw and banana pudding served in a jar that tastes just like childhood (but better). Every bite feels intentional.

It’s barbecue with heart, history, and just the right amount of heat. Riot BBQ isn’t just a meal, it’s a moment worth lining up for.
