Despite much handwringing on the part of brick-and-mortar restaurant owners, it appears that the food truck revolution is here to stay — and with it, the notion that wherever at least two or three gourmet food trucks are gathered is a pretty good place to have a party. In Oakland, there are bigger food truck gatherings and ones that are more popular. But for the past three years, Bites Off Broadway has been in a class of its own in terms of providing a low-key, community-minded experience. The lines for the six of so trucks that gather in front of the Studio One Art Center each Friday are rarely more than a few customers deep, and there’s a big stretch of lawn where families and friends can sprawl out on a picnic blanket and enjoy the late afternoon sunshine. There’s room for the kids to run around and, often, lawn games and live music. What’s not to like?
