We ate at the little diner inside Mariana's on the suggestion of a friend. The food itself was OK. We had the taqiza family combo- 10 tacos, beans, rice, and salsa for $15.99. The price was great, but the food was just ok. The beef was overcooked and dry. The rice was alright, and the beans were actually pretty good.
The diner itself was super crowded and it was hard to hear, and as a result, hard to order.
I will give Mariana's a second try and let you know it goes!
