A food truck serving Filipino cuisine wheeled across the border from San Jose to make its debut in Milpitas last night—in the old Mervyn's parking lot.

What's the allure, you ask? The WOW Truck doesn't keep a regular schedule. Instead, it uses Twitter to let customers know where to find its signature silog and turntable music.

And while mobile food trucks are not new—Korean taco truck MoGo BBQ and karaoke ice cream truck Treatbot have graced the Meryvn's lot as well—The WOW Truck could be the first to feature silog. Silog is a tried-and-true Filipino matrimony of fried egg, garlic fried rice and a choice of meat—pork sausage, corned beef, chicken, tapas or Spam.

"The one that is selling the most right now is the longanisa (pork sausage)," said Ronnie Hernandez. He and his girlfriend, Crystal Aranas, came up with the idea of the musical silog truck while working at his family's  grocery store after his mom got sick.

"My girlfriend and I were there managing the store, and we thought about the idea of having a late-night silog spot, because there's not much of any late-night spots for Filipino food in San Jose," Hernandez said.

Within weeks, Hernandez and Aranas turned their ideas into reality. They called the late-night spot the "Window." Patrons went up to the window, ordered their food and left. The concept was simple, but genius.

After Hernandez' mom suffered a heart attack, the "Window" was put on the back burners until three months ago, when Hernandez' friend and renowned San Francisco chef, Tim Luym, talked him into opening a gourmet food truck that combined his and Aranas' "window" idea and Luym's culinary skills.

"It sounded like a good idea, and right now with what's going on with food trucks, it kind of made sense," Hernandez said.

The WOW name came from the "window" concept, but on wheels.

"I wanted it to be short, and I was just driving and brainstorming and putting words together, and that's what came out," Hernandez.

If the bright yellow-and-red design isn't visible enough, those passing by will hear the blaring music from the turntables inside the truck.

At first, the idea of having "music, food and eating" started with an iPod that would play from the truck, but the idea started evolving, and Hernandez wanted to put a whole turntable system inside the truck.

"I don't think anyone's ever done that," he said. "It's a little tricky putting it together, but it works."

Hernandez and Luym used to DJ together, so the two have connections with people associated with music.

"Right now we want to do a full cross-marketing campaign with DJs and different networks of groups of friends," Hernandez said. "We want to associate our name with DJs, artists and different types of clothing stores to cross-market each other."

Rondo Membrere, owner of 3rd Floor Collective, a media company, and close family friend, said the turntables are a creative addition to the food truck.

"They're now able to feature many local DJs from around the area," Membrere said. "So not only are you enjoying good food, you're able to be accompanied by a professional DJ, playing a variety of different music at the same time."

Although the menu is limited, what WOW offers is a spin on traditional silog by incorporating different spices and flavors, and different types of meat, like New Zealand corned beef, and a unique barbeque style of cooking.

"The food itself is very unique yet simple," Hernandez said. "You can't go wrong with fried egg, a type of protein and garlic rice. You can eat it for breakfast, lunch and dinner."

WOW is the first food truck in the South Bay to cater to the Filipino community.

Jeff Gunabe, a San Jose resident, said he went to the grand opening of WOW, because he heard about it on Facebook and Twitter.

"I'm Filipino and I love Filipino food," he said. "You've got to support local businesses, and this is a pretty innovative concept, with the design of the truck and the DJ booth. It's great; you can listen to music while you wait for your food, and you can dance off the calories."

Besides Milpitas and San Jose, WOW plans to visit cities such as Union City, Hayward, Oakland and Berkeley.

"Since they're mobile, they can travel wherever they want, allowing them to reach out to the different communities in their area," Membrere said. "Unlike other cities, such as LA, the food truck scene here in the South Bay is young, and The WOW is bringing a fresh new vibe to the Bay Area."
