Guisados in Boyle Heights is opening Friday from 8 to 11 a.m. for a special test run of the restaurant's future breakfast menu. The restaurant, known for its hand-made tortillas and stewed meats, is planning on serving breakfast at its soon-to-open location in downtown. Guisados made the announcement on Instagram by posting a photo of a fried egg, but no details were given on what breakfast items would be offered. However, the post did say all items would be sold for 50 cents each. When Guisados cofounder Armando De La Torre spoke with The Times' Betty Hallock in January, he mentioned home-style chorizo con huevos and more egg dishes and tacos on hand-made tortillas as possible breakfast items. Guisados will also be testing its Stumptown cold brew horchata Friday. 2100 E. Cesar Chavez Ave., Los Angeles, (323) 264-7201, www.guisados.co.
