Jr. Mex is the take-out division of Super Mex. This local Mexican food chain is a Long Beach institution, serving a range of Mexican eats since the mid-70s. Jr. Mex can reduce the wait time for the very famished while still offering the vast majority of Super Mex's menu. Burritos undoubtedly are the most popular, but there's a very extensive supporting menu that will appeal to many tastes in south-of-the-border cuisine.
