On the Grid : Barnsdall Art Park
"Home to the Hollyhock House, the park and the aforementioned house were the brainchild of Aline Barnsdall and Frank Lloyd Wright (both two individuals worth losing a few hours to on Wikipedia). The park sports some of the best (free) views of the surrounding Los Angeles skyline and is markedly less crowded than the more touristy Griffith Park. While the park is great for a cheap date idea, the house is also worth the price of admission and the occasional event or art exhibit are also worth making time for." - Cris Cimatu
