La Sirenita, which translates to "the little mermaid," is a cheerful Highlandtown restaurant that serves great Mexican cuisine. There's nothing fancy here, just really good versions of your favorite Mexican dishes. Its tacos are awesome, as are its posole, huaraches, and fajitas. The menu at La Sirenita is large enough to keep you busy trying new things to find out what your favorite is. The horchata it makes is excellent too, so make sure to wash your food down with a cup of the classic cinnamon-rice drink.
