Fleet Week means a big boost for sales.
"The Blue Angels flying over, the sense of buzz that Fleet Week brings, the amount of new people to the neighborhood, is something we've always thrived on," DiAntonio said.
At Sam's Grill on Broadway, Emad Elshawa says his business is up about 25% this week.
"We came out to Sam's for a burger," said Nick Gallegos of Hayward. He brought his daughter to Fleet Week.
Gallegos says he spent about $100 around the City on this Saturday and that this special event is a big deal for San Francisco.

Back to all the visiting men and women in uniform...
Jersiah Gurly and Imari Augustus are sailors with the U.S. Navy and were grabbing a slice at Pizzelle Di North Beach.
For many sailors and marines, it's their first time in San Francisco.
"It's pretty cool--lots of different food cultures, lots of place to eat at," Gurley said.

"I've never been to SF before. When coming in, got to see Alcatraz and Golden Gate Bridge. That was cool," Augustus said.
"We eat, walk around, go little sightseeing at spots like Golden Gate Bridge, Alcatraz, the piers," said Ricky Passians with the U.S. Navy.
At Vesuvio Café in North Beach, bartender Jimmy Mauberret gets a kick out of welcoming all the young service members.
"We had a lot of people last night--a lot of sailors. I played in the 'In the Navy' by Village People--which was funny because those kids, they haven't ever heard that song. It was probably first time they heard it," Mauberret said. "Fleet Week is great for business everywhere."
