The corner space at 20th and Santa Monica Blvd. in Santa Monica, in what is currently the Gateway Hotel, has had a rocky past.  First it was an IHOP.  Then, for a minute, it was Rudy & Hudson California Diner.  Now something exciting is on the way.  An ABC application informs us that a new eatery is intent on moving in, but there’s no business name listed.  There is however a design review notice that shows an artist’s rendering of the new place, and gives it a name:  Socalo.  And according to this article in the Santa Monica Daily Press, Socalo will be none other than Mary Sue Milliken’s and Susan Feniger’s triumphant return to Santa Monica, after the demise of the iconic Border Grill.   I can’t wait.
