Jerry's Underground ispart open-air up-market salon, part game preserve, and part garden party. Featured in USA Today and several other news sources, this hair salon also has a National Wildlife Certification protecting the various birds that flutter around the attached (and immaculate) garden. The salon itself has Italian tile and luxe seating; huge folding glass doors can be crimped into the corners on nice days allowing the salon to spill out into the bird-and-flower-filled courtyard. With 40 years of salon experience, owner Jerry was once known as the "Rocky Balboa of hairstyling" back when he was the only one-man shop in Harvard Square, fighting against the larger franchise operations. The atmosphere is relaxed at Underground, which is also attached to the owner's home. Famous, skilled and having fun with life, a more enthusiastic business owner is hard to find in Somerville.
