There seems to be a load of restaurant activity going on in Beverly Hills lately…  Here’s the latest:  design-your-own-burrito restaurant Chipotle Mexican Grill is hard at work taking over the now closed Baja Fresh space at 475 N. Beverly Dr. in Beverly Hills (on the corner of Little Santa Monica).  And yes,  there already is a Chipotle down the street at 224 S. Beverly.  Unfamiliar with the ubiquitous Mexican chain?  Acquaint yourself here: chipotle.com.
