Entertainment Law to Be Studied: An ordinance allowing live entertainment in restaurants located in limited commercial zones will be considered by the City Council on Monday. The ordinance would change city zoning laws that do not now permit entertainment in these areas because they border on residential zones, according to Jerry Blum, planning division manager. Entertainment, such as a pianist or other musical act, would be allowed with a conditional use permit, but restricted to restaurants of at least 2,000 square feet of floor space and only in dining rooms during dining hours and without amplified instruments. The ordinance also requires that additional parking be supplied for the expected increase of patrons. The ordinance has been approved by the city's Planning Commission.
