Juan Luna, owner of the downtown Gainesville restaurant Luna’s, will have to stay at least 50 feet from rival restaurant owner Scott Dixon for the foreseeable future.Luna, who was charged with simple assault for pointing a gun at Dixon in an altercation last year, pleaded guilty in state court Wednesday to two misdemeanors connected to the incident.Dixon owns another downtown Gainesville restaurant, Scott’s on the Square. He told The Times last year that the two men had argued in early June 2011 over Luna’s hiring of Dixon’s former head chef.Luna, on the other hand, said he stopped to talk to Dixon on his way home when Dixon “got all bent out of shape.”A report compiled by Gainesville police said Luna then got a nightstick from his vehicle and approached Dixon in a threatening manner. After the two argued briefly, Luna reportedly drove away only to return a short time later.
