Mercados Marias 1 is a Mexican-Latin American market that offers a great variety of meats, vegetables, fruits, and traditional goods. While the cashiers are noted to be nice, some reviews mention that the place can be dirty, with a restaurant area that appears unsanitary and food that looks old. The quality of the bread is criticized for being subpar, with all sweet bread tasting the same. However, the market is praised for its affordable prices on certain items, especially for tacos and carnitas, which many customers find better than local restaurants. Overall, it is a popular spot for those looking for authentic street tacos and a wide selection of Hispanic products.
