If you want to witness what architecture is about, visit SCI-Arc. This is where I went to school ,and I can tell you there is not one day that you will not be surprise what goes on inside this school. From open to the public lectures every wednesday to galleries and installation, and not to mention the student work.
This is a great place to walk around. It really feels like a mini Lake Shasta or something tucked right up in the Hollywood Hills. Ornate statues on the bridge and sweet smelling trees. If you squint you almost feel like you're not in the middle of a massive city.
Jacknife has an amazing collection of tapes, vinyl, and used gear like stereos and tape decks. The quality is top notch, and if you can't find something out on the floor, chances are they'll have it in the back. If you see Trevor, tell him I sent you.
Dylan's Candy Store is located in the heart of the Grove. You can find the any kind of candy you can imagine. I always feel like a little kid in that store and attack the teeth gummy.
