St. Louis’ Flying Saucer Saved. Preserving mid-century modern architecture has become a hot-button issue around the country as aging icons are becoming old enough to be called historic.

Now, it looks like the building will once again become a burrito stand as the developer has confirmed the building will house a Starbucks and a Chipotle. NextSTL has the details.
