If you don't do anything else, get some drinks at Barrio! I had the Marigold and Margarita Perfecta and they were both pretty stellar.
As far as the tacos, I thought they were just ok.
Prices are pretty fair with the build your own taco starting out at $3, any extras will cost you, but not much. BUT their sides are super tiny, they literally come in a cup that you'd out condiments in at a hot dog stand.
