Soviet authorities closed down the second of two new Pizza Hut restaurant in Moscow in a dispute over local rules that highlights problems facing Western firms in the still highly regulated Soviet economy.

Last Thursday the local sanitary authority closed the flagship Soviet Pizza Hut 10 days after it opened. That restaurant was allowed to reopen on Saturday, but Wednesday the other Moscow Pizza Hut was closed down by the same department.The official Soviet news agency Tass quoted a sanitary inspector Tuesday saying Pizza Hut did not submit plans to the proper local department before opening and the kitchens violated several regulations, including a rule on the distance between raw vegetables and prepared foods.
