While Las Delicias is a convenient and fast place to get a meal, you could do better at pretty much any other Mexican restaurant in town. The service is consistently fast (often to the point of feeling a bit rushed) and food arrives quickly. However, most entries are bland and uninspired -- tamales frequently come out broken, flavorless, and nearly indistinguishable in coloration from the beans and rice on the plate. Nachos are edible, but nothing that can't be found elsewhere. Drinks are about the same price, if not more, than a lunch plate and don't stack up to other places, such as Rio Grande, or even Wahoo's. If you need a quick Mexican fix, Las Delicias is a choice, but you can find better.
Pros: Quick, cheap, convenient
Cons: Lacking flavor, generally poor food
