I’ve mentioned in earlier posts that I’m a big fan of mid-century modern design, and fortunately there’s plenty of it to see around San Diego, CA, my hometown (born and raised). A great site I highly recommend is modernsandiego.com. Though the site itself could stand for a more modern/user friendly design, it does provide some great information on almost all of the great modern architecture within San Diego county, as well as the architects who did such great work.
If you go to the current home page and scroll down about 3/4’s of the way, they even have a post about Jack In The Box restaurant buildings. The cool news is Jack In The Box is restoring one of their restaurants back to one of their mid-century designs, circa 1956. If you live in San Diego or come to visit, I recommend going to take a look, located in the Hillcrest neighborhood on Washington and Front streets.
