West Portal is a small neighborhood that is similar to the adjacent neighborhoods of Forest Hill and St. Francis Wood. It is a middle to upper-middle class primarily residential area of the City. The neighborhood's main corridor West Portal Avenue serves as a principal shopping district of southwestern San Francisco. Because of its small size and mom and pop stores, restaurants, and saloons, the neighborhood is often described as having a village atmosphere. The neighborhood is served by a branch of the San Francisco Public Library. Like Glen Park, the neighborhood is one of San Francisco's metro-centered communities. Though small the neighborhood has many restaurants, salon and nail services, and a movie theatre among other businesses. The frequent fog helps keep the area green in the usually rainless summer months, and on a clear day the park above the tunnel provides a view of the Marin Headlands and the Farallon Islands in thePacific.
