Holy Grill is located in a section of San Francisco known to designers as SF Design Center's Showplace Square and Galleria. I've recently been contracting with Roche Bobois on a design project, which is just a couple of storefronts from Holy Grill.
It's not a very large restaurant, with very scarce seating. I worry about this, because I think business could really pick up if they expanded. To my knowledge, there's only one location.
Verdict: An excellent, excellent burger with tangy special sauce and extremely fresh ingredients. Reminiscent of 'In-N-Out' but with better, bigger ingredients. Highly recommended, good luck finding seating during peak hours though.
