This is probably not a restaurant you'd want to frequent.

In a video that has gone viral, a bunch of rats are caught running up a hole in a ceiling when the lights in a restaurant are turned on. And when we say "a bunch of rats," we mean it. It's hard to get an accurate gauge on just how many there are, but it's safe to say there are more than a dozen -- perhaps even two.

And the thing is the rats slither their way to the pole and up through the hole en masse. It goes on for several seconds, making you think the creatures are camping out in kitchen like it's a summer getaway or are on the hunt for some food. Either way, it's a real mystery, a true Secret of NIMH.

It's unclear where the restaurant this took place is located nor what the name of it is. We're guessing, though, that it serves rat-atouille.
