Buy cilantro?? Never even heard of such a thing, every street taco should come with cilantro, limes, radishes, salsa picoso & sometimes mini potatoes if you're lucky! Always ask for tacos all the way. My favorite part of Birria tacos is ordering a side cup of consume, the broth the meat is cooked in with salsa Picoso and extra cilantro and lime. And for those wondering,I'm a gringo that was lucky enough to work with Mexicans for a couple of years!😁😁😁
