Miami-Dade Mayor Carlos Gimenez said he will be signing an order today closing restaurants in the county nightly at midnight.
"We've seen some restaurants taking advantage of that order and basically turning themselves into nightclubs after 12 o'clock," Gimenez told CNN’s Jim Acosta.
"They are converting themselves into nightclubs after 12 o'clock and we have seen a sharp rise in the number of young people," he added.
Gimenez said that not complying with the order is a misdemeanor and violators can be fined and spend up to 180 days in jail.
Official conducted 7,000 inspections on businesses today to "make sure they were complying," he said.
"The vast majority are complying but again we think it's more of a problem with young people, they're not complying," Gimenez said.
