Mel Gibson is back in circulation.  Exhibit A:  Dining out with a pretty woman last night at Culina restaurant at the Four Seasons Hotel in Beverly Hills.

We've asked around ... and no one seems to know who she is and whether it's about business or pleasure ... or just friendship. 

Here's the thing.  She looks dangerously like one Oksana Grigorieva.

Hey Mel ... sometimes looks can be deceiving in a good way.
