Eighteen thousand five hundred square feet. That's a lot of space to fill. That didn't intimidate Hector Medina when he moved El Torito up the street three years ago. Since then he has managed to fill the space in ways that only a Mexican market owner can. As soon as you walk in, you're assailed by the loud beats of reggaeton or norteo and the buzz of activity from shoppers and patrons of El Torito's in-house taqueria. You want Mexican groceries? Hector's got Mexican groceries. Fresh crema Mexicana and aged queso cotija. Chiles galore, tortillas too. And half an aisle devoted to veladoras, Mexican votive candles. Not to mention the baptism outfits and quinceaera dresses, cowboy boots and hats. The joy of discovery awaits you in aisle after aisleit's as close to Mexico as you can possibly get without leaving St. Louis.
