In the Observer’s newest online series, “Trucked Up,” Features Editor Rex Sakamoto ventures to the DUMBO section of Brooklyn to have a taste of Korilla BBQ, a food truck that specializes in Korean fusion cuisine. Rex enjoyed the cho sum bowl loaded with kimchi fried rice, bulgogi, kimchi, vegetables, and korilla sauce. If you want something spicier, try the killa sauce. Check out their website at korillabbq.com to find the truck’s current location.
