This neighborhood fruit juice and dessert store in Lincoln Heights is basically a Swiss Army knife of Mexican treats: bionicos, licaduos, mangonadas, agua frescas, sundaes—you name it, they’ve got it. They’re especially famous for their nieves, silky smooth sherberts that come in milk-based or fruit-based flavors (watermelon, tamarind, melon, and mamey are some of our favorites). But you shouldn’t leave without sampling the shop’s namesake beverage, a tart and tangy fermented corn drink known as tejuino, which Los Reyes serves with a big scoop of highlighter-green limon sherbet on top like a float—the ultimate hot weather refresher.
