Located at the intersection of Mason, Greenwich and Columbus Ave. near Washington Square in San Francisco, the secret is to walk through the small restaurant and take the stairs down to Belgian. Not only are there over a dozen Belgian and Trappist beers on tap but the menu book has hundreds of other, very interesting, beers. In addition to several Belgian beers, we sampled a truly outstanding beer from Italy and a dry, crisp ginger beer (7%) from Japan.
