Diddy: Class all the way during dinner at The Lion

Talk about service!

Diddy and girlfriend Cassie's dinner at The Lion on Sunday night was first-class all the way.

The couple rode up in a swanky gray Maybach, and "their driver entered the restaurant first to make sure the couple's table was ready," a witness told us.

Once it was, the duo made their entrance, with Diddy "carrying his own glass of wine," the spy said.

They sat in a back booth and dined on calamari, a burger and the pork chop.
