A couple of weekends ago, I went to the Asian Heritage Street Fair in San Francisco’s Tenderloin neighborhood. And for the first time, several food trucks were parked in one section of the fair.

Selected for their Asian offerings, there were the well-known food trucks such as The Chairman and Seoul on Wheels. But there were also two new trucks that I never heard of or never had a chance to try their food.

The first is a fairly new truck called Koja Kitchen, which emphasizes Korean and Japanese cuisine. Its main offerings are Korean-style meats sandwiched into a rice bun. The rice buns aren’t steamed buns made of rice flour. Instead, they’re almost like rice crackers, except freshly rice kernels with a crispy edge.

I tried the Korean BBQ Chicken with Pineapple ($5.50), which included strips of Korean BBQ chicken with a whole caramelized pineapple slice. As you can imagine, it’s a bit messy to eat with the rice buns, which do fall apart a bit (imagine eating a musubi rice ball) but was so worth it because of the nice flavor of both the chicken and pineapple. (I thought the pineapple would be too sweet, but it wasn’t.)

The second truck I tried was JapaCurry’s food truck, which has been around for a few months serving up curry around the Financial District. I ordered the pork tonkotsu curry ($7), which as you might know is the only real way to eat Japanese curry. The fried tonkotsu slices were well done, although a bit dry.

The curry on the side was tasty, with a nice sweetness to it, albeit a bit on the oily side. Still, it was pretty good for something being dished out from a truck.

I was excited trying these two new trucks, especially Koja Kitchen. Their products show that food trucks can be more than fusion tacos.
