El Camino in Fremont is not your family Mexican, however I wonder their authenticity. That being said, I still love their food and drinks.
This is the place to have a mojito (or two or three..) and enjoy a great dinner while watching the hipness that surrounds you. Yes, El Camino is about the food, but its also about the trendiness. Granted the food is good but limited choices. I tend to stick to the carne asada tacos. On my last visit we tried a couple of apps, which were tasty, but nothing revolutionary. We also shared a lemon tart with a coconut cream which was outstanding (and the only dessert left on the menu on a Sunday evening).
I haven't made it their in the summer, but from my understanding that's really when it becomes a happening place.
