I'm all about Taquerias - I feel like it's a personal mission to visit every one in the Cincinnati area...
It's very small - there are a few tables in the first room and maybe 3-4 in the side room. They will come to your table and wait on you. Our server was super friendly - answered any questions we had and was really great. There were also many Hispanic people eating there - which gives you a sense of its authenticity and the fact that the food is going to be good.
And I know - it's super American of me - but I like cheese and sour cream and luckily they were nice enough to bring me some.
Why Should You Go? If you want authentic - you have to go. It's also cheap and tasty!
