Street parking is available as well as a parking lot adjecent to our building; however, we encourage customers to walk, bike or take public transit. There are ample bike parking bars up the street in front of Toad Hall and we are just a block from the Castro MUNI Metro Station. The 24-Divisidero and 33-Stanyan busses stop just less than a block away from our front door.
