I finally did few "obligatory tourist stops" during my trip to LA like Walk of Fame and Chinese Theatre - Hollywood Hand & Footprints.
The Hollywood Walk of Fame is one of those iconic places that you have to tick off and take pictures of your favorite fans and Hollywood Hand &Footprints with older signatures and hand-prints in the cement you really feel the past history of the place. Very cool :)
At Griffin observatory with incredible panoramic views of the LA I was able to see the famous Hollywood sign though it's a considerable distance away. There is a museum with best space science and statues of great physicists you can take photo with :)
