    Service was fine, I was the only one in the restaurant but my food took around 20-30 minutes, (which is fine if the food was good), but unfortunately my meal was not too tasty. I ordered the Birria Tacos hoping it would be great and flavorful. The tacos were tasteless and bad soggy and the consume was just broth with onions in it. Overall, not the best place to get Mexican style food, I’d love to try again if they change up the recipes and style of cooking.

    Went yesterday at 1 am and the worker had the worst attitude known to mankind. I asked for honey glazed chicken and he gave me steak instead, the menu is completely wrong and they charge extra for things that are not shown to be extra. The fries are overcooked and tasted disgusting.

    I wish I took a picture of my food because it was bussin, and they give you a lot for the burrito bowl. The cook is really proud of their food and it actually makes a big difference. Everything looks really clean and looked after. I’m gonna go back and order their chicken wings because they look so fresh, they also have so many options for dessert as well. So definitely recommend
