The Harbor House is on Pacific Coast Highway in Sunset Beach, just beyond the famous water-tower house. It is open 24 hours, and generally has a waiting list - because the food is good and the prices reasonable. It is one of our Not-Local favorites.
The route to generally goes along PCH or Anaheim street (to minimize the enroute time). The return usually goes along the Long Beach bike path/LA River bike path - less traffic and more scenery. The LA River bike path has been closed for repairs - but might be reopened by the time of this ride.
