Harry Styles Power Lunch With Cindy & Rande

Harry Styles is either an honorary family member to Cindy Crawford and Rande Gerber ... or just a great drinking bud.

The trio did lunch -- with Cindy and Rande's daughter Kaia -- at one of their restaurants ... Cafe Habana.

No word what was on the agenda for this sit down, but 22-year-old Harry's been in with the 50-something Gerbers for a while. He scored a few boxes of Rande's Casamigos tequila for his birthday in January. Maybe the kid wants a piece of the agave game, or maybe he just needs a fresh case.
