For diners, there are benefits to the Tweets beyond just knowing where to find the eats.
Kogi is using the service to maintain the Californian tradition of restaurants having secret menus one must be in-the-know to order from (such as the hamburger joint In-N-Out). On the side of the truck, Kogi's menu lists a few items, including tacos and burritos stuffed with Korean short ribs, spicy pork, chicken and tofu. But keep up with Kogi's Twitter feed and the options multiply.
"We do that because it's fun to have something different and experimental available every day," says Prasad, adding that the truck wouldn't have as many followers if it didn't provide new options.
Some recent specials that weren't on the menu featured kimchee (a spicy pickled cabbage traditionally eaten as a condiment in Korean dining) stuffed into quesadillas and as a topping for Spam sliders.
"There's some really high end food coming out of food trucks," says Goldman, making them a natural place for Twitter to gain ground. "This type of immediate information and constant update is going to increase."
