I've probably blogged on Casa Vega but I vote them to be the Best Mexican Restaurant in California.
When you walk in, its like stepping into the 70's. An old nostalgic scene out of the valley. Its dark, low key and all out good times. Any person that lives in the valley knows of this local spot.
This place has the best Margaritas, Salsa, food and Mariachi band.
If you haven't been to Casa Vega, you haven't experienced life.
