Cinco de Mayo shouldn’t be one of those holidays that can sneak up on you. Much like the Fourth of July, the date is actually in the name of the holiday.

But this is one of those years where it just might because May 5 falls on Monday. That means nearly all the hoopla in San Jose will take place the weekend before, May 3 and 4, with some folks no doubt turning it into a three-day celebration. Maybe we can consider them Cinco de Mayo observado and Cinco de Mayo tradicional.

In any event, there’s quite a lot going on in San Jose this weekend to celebrate:

On Saturday, there’ll be a lowrider car and truck show in front of SAP Center from 8 a.m. to 4 p.m. It’s free to swing by and check out the custom vehicles and entertainment, but plan your trip accordingly as West Santa Clara Street will be closed from Stockton Avenue to Highway 87 and Barack Obama Boulevard will be closed from St. John Street to San Fernando Street until 6 p.m.

There’s a parade planned for Sunday, going along King Road from Alum Rock Avenue to Story Road. It starts at 9 a.m. and is scheduled to last a couple of hours. That will be followed by a festival at Emma Prusch Farm Park, with live music, traditional dance and more lowriders on display from 11 a.m. to 4 p.m. Both events are sponsored by the United Lowrider Council of San Jose and the office of City Councilmember Peter Ortiz.

There’s also a celebration scheduled for downtown San Jose, but this one will not include a parade. There will be a free festival at Plaza de Cesar Chavez from 11 a.m. to 8 p.m. with food trucks, live music and dance performances.

CITY HALL HANGOUT: There were a lot of City Hall badges at the ribbon-cutting last week for downtown San Jose’s Sixth Street Burger, which has become the lunch spot of choice for city staffers. That’s not a stunner, given that the new eatery is a hop, skip and a jump across Santa Clara Street from San Jose’s tower of political power. It’s probably drawn the biggest share of City Hall employees since Fourth Street Pizza closed a few years ago. (Rollati Ristorante, however, maintains its grip on the happy hour crowd.)

Abram Chandler, who co-owns the restaurant with Ricky Hobson, grew up just a couple of blocks away from its location on Sixth and Santa Clara Street on the ground floor of the historic Medico-Dental Building. Chandler is actually splitting his time, as he’s been the owner of Crown Plumbing in Willow Glen for the past 20 years but was passionate about starting a restaurant. He considered doing pastrami sandwiches for a while, but settled on burgers, and the menu — smash burgers, hot dogs, salads and fresh-made milkshakes — has been a hit with customers so far.

“City Hall has been really supportive, with people coming in for lunch every day,” Chandler said. “The neighborhood’s been really supportive, and I’m really grateful.”

PARTY LIKE ITS 1985: If you were near the San Jose Marriott on Saturday night, you might have noticed an unusual number of pastel shirts, leg warmers, checkerboard Vans and skinny ties. Downtown San Jose did not step back into the mid-1980s, but the guests at City Lights Theatre Company’s Neon Groove Ball totally did their best to make it seem that way.

City Lights Board President Clint Moore decked himself out like Marty McFly in “Back to the Future,” while Executive Artistic Director Lisa Mallette channeled her pink and bubbly side as 1980s Barbie. There were a few Madonna’s, a Boy George and a Pee-Wee Herman, and I’m pretty sure some of the crowd might have been wearing items they actually donned in the ‘80s.

Santa Clara County Supervisor Betty Duong — who was born in the 1980s — wore a dress of her mom’s from that decade, paired with an appropriate denim jacket complete with an MTV button pin. She also boosted up the energy by announcing a $10,000 grant for the downtown San Jose theater company. The audience also raised more than $200,000 through the auction and direct donations, including a $100,000 matching grant from an anonymous donor.

By the way, City Lights will be leaning into the ‘80s again July 17 when it opens its summer show, “Head Over Heels,” a jukebox musical featuring tunes from the Go-Gos.
