McDonald's said it would be appealing the court decision to keep the first four restaurants closed, and was reviewing all the regulator's concerns as it tries to re-open its outlets.
"Our main priority is to serve our customers with top-quality menu items," said a McDonald's spokesperson. "We have extremely high standards in Russia, just like all our restaurants around the world."
The Russian regulator -- Rospotrebnadzor -- will continue to conduct checks at McDonald's restaurants across the country over the next few months, said the spokesperson.
