The rapper's popular joint, Escobar Restaurant & Tapas, was ordered to close its doors just Monday night after Georgia State Police paid the restaurant a visit. According to a police report, obtained by TMZ, officers say they drove by and "noticed that the location was rather loud, busy, and occupied to be operating as a restaurant at that time of night."

As you can see from some of the videos posted to the Escobar Instagram account, the place was PACKED. You can see people dancing, ordering bottle service, smoking hookah with virtually no social distancing happening. As the night continued, you can even see a long line start forming outside the entrance.

Cops say police arrived and "spoke to the manager before shutting the location down as it was violating executive orders regarding protocol issued due to COVID-19."

As we reported ... 2 Chainz initially said his restaurants would open when Georgia allowed limited-service back in late April. But, the rapper changed his mind -- opting to feed the homeless instead -- and said they'll wait it out a little longer before bringing back his staff.

Several weeks later, Georgia updated its restaurant reopening guidelines ... limiting dine-in service to 10 patrons max per table and allowing 10 patrons inside per 300 square feet of public space. This is all in addition to social distancing too.
