Just outside of Sydney, Australia, you may come across the Seoul Hoikwan Restaurant in the neighborhood of Belfield. Submitted by Mike, I really enjoy the classic architecture of this UTBAPH. Trapezoidal windows with exterior windowsills that drip nearly down to the ground are a nice touch. This place is clearly just a quick sandblast away from being back to its original form.
Built in 1970, this is actually the first Pizza Hut to have been built in Australia. Before this, it was all vegemite sandwiches for the fine people down under. Hard to believe that this has not been turned into a museum, but I guess some people just don't appreciate history.
