La Juanita is indisputably one of the most iconic restaurants in Siouxland. But how does the taqueria stack up as an eatery for families with kids? Here's our take: Where is La Juanita? La Juanita is at 1316 Pierce Street near downtown Sioux City. You can also find them online on Facebook ! When is La Juanita open? La Juanita is usually open from 9am to 1am daily and until 2am Friday and Saturday nights. Hours during the COVID-19 pandemic may vary, so please check their FB page for the most up-to-date information. Atmosphere at La Juanita La Juanita's is reasonably clean and very well lit, with cheerful decor, an open kitchen you can watch from the line, and a jukebox playing Mexican music (so bring a few coins to liven up your wait!). During busy times, the line often extends up the stairs and even out the back door towards their parking lot on the East side of the building, so I recommend going with kids during off hours and/or bringing a baby carrier to contain little on
