La Sirenita offers traditional Mexican on the cheap with no thrills. The dining area is tight alongside a busy, open kitchen and a soda case with plenty of authentic flavors in glass bottles, including Sangría without the alcohol. Huge bowls of soup (shrimp or beef tripe or hominy with pork or fish) come with a platter of hard corn tortillas and veggie garnishes, and at just around a ten-spot, they make for a hearty meal. A list of beef and chicken specials includes fried quail; all specials are served with yummy refried pintos and corny yellow rice, as are the spicy enchiladas with red or green sauce, chile rellenos, and chilaquiles. Seafood also plays a role on the menu--La Sirenita means mermaid--with ceviche, oysters, grilled shrimp, and fried fish. The à la carte burritos and simple tacos with fresh parsley, chopped white onion, and flavorful meats make for a nice lunch, as do the large meat-filled sandwiches. They promise a BYOB license soon, so until then, save the Coronas with lime for before and after.
