This restaurant serves some of the most incredible South Indian Food in the Bay Area (actually, best I've tried). Saravana Bhavan is very easy to miss. If you are headed the wrong direction on El Camino the sign is written in Hindi (I think).
Their focus is clearly on the food, and you are comforted to know that not a penny of your check is being spent on the decor.
On weekends, the parking lot fills with Indian families milling about waiting for a table. I don't think that there could be a stronger endorsement of the restaurant than that.
