Monday night, the star and his entourage of 80 went to San Rafael Puerto Rican restaurant Sol Food.

Bad Bunny greeted staff and took pictures.
"I wanted to go up to him and tell him I'm one of his biggest fans, but since I was at work I was like, alright I've got to hold it down, be professional," said Francisco Gomez, Sol Food manager. "It's like having the Oprah come and visit us here. So it's a great feeling to know that a Puerto Rican artist came to our Puerto Rican restaurant and brought Puerto Rican people to come in and enjoy our food."
