We present preliminary results from 1.5″ resolution IRAM interferometer maps of CO 2↛1 emission in the central few arcseconds of NGC 1068. This study is unlike other studies of the CO content of this galaxy since it resolves for the first time the central dense gas concentration seen previously in HCN observations. The HCN `disk' is resolved into two prominent peaks symmetrically located ~1″ from the S1 radio peak. These peaks are likely tracing gas located on x2 orbits at the Inner Lindblad Resonance (ILR). The kinematic structure is also very complex with three distinct velocity components visible in the central ~2″.
