fish tacos on the strip
Lolitas Cantina at Town Square offers fish tacos using a variety of preparations; grilled or fried. Eaten there several times and the tacos are consistently good. Their chips and salsa are pretty good too.
Not sure if Border Grill offers fish tacos (Mandalay Bay), but they do offer a variety of seafod.
