Puig flagged down the bus (super comfy seats, btw) while eating at Villa Blanca in Bev Hills on Friday -- and got onboard to take pics and shake hands with the guests ... one of whom happened to be Gonzo!
Everyone had a blast and Puig was super cool -- but do ya think he knew he just shook hands with a 5-time MLB All Star (and former Dodger)???
