It was good... possibly great. Coming from San Diego, it's hard to satisfy my taste, but this place is authentic, especially considering we're in the midwest. I only had the street tacos, which were great, and yes, you can definitely mess up a dish that only consists of 4 ingredients. It's fast, you get chips and they serve up coke in a bottle.
I'll definitely be back to try out the other dishes; although, there really is no reason to stray away from good tacos.
