The Red Lion Tavern has been a neighborhood tavern in Los Angeles for over fifty years (which is a long time for L.A.), and continues to serve as a landmark for traditional German food, a wide selection of German beer, and cozy Old World atmosphere. Plus the waitresses all wear lederhosen, and it's blocks away from my parents' house.
This restaurant has been a Hollywood landmark for over 60 years. The interior looks like time has stood still. Go to the reastaurant area to have a nice piece of prime rib, and after dinner move to the lounge area where Elaine and Marty sing their oldies but goodies. Some believe that their version of "Staying alive" is better then the original.
The Magic Castle is a nightclub for magicians and magic enthusiasts, as well as the clubhouse for the Academy of Magical Arts. It bills itself as "the most unusual private club in the world." A typical evening features several close up magic and stage illusions. Formal dress is strictly enforced and you must either be a member or be invited by a magician. The lobby of the Castle has no visible doors to the interior, and visitors must say a secret phrase to a sculpture of an owl to gain access, exposing the entrance to the club. What I enjoy most is walking through the corridors and staring at the posters and photographs of the history of magic.
The LA Opera at the Dorothy Chandler Pavilion on Grand Street in downtown LA is a must during the fall and holiday season when they have a solid lineup of opera and ballet. Very inspiring.
