Is this a Juxtaposition, or What?

This photo was taken the night of the Foodbuzz San Francisco food bloggers dinner. I'm posting it because I don't believe I've used the word "juxtaposition" in the blog yet.

I like this photo because in one frame you have San Francisco's oldest restaurant, the Tadich Grill, right next door to Perbacco, one of the City's newest.

The contrasts in colors, shapes, textures, signs, fonts, and materials are fascinating to me. As I snapped the picture I wondered if Perbacco will still be there in another 156 years?
