Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On December 14, 2015, Del Taco Restaurant Properties II (the “Partnership”) consummated the sale of all the properties owned by the Partnership for a total purchase price of $8,075,000 pursuant to the terms and conditions set forth in the Purchase and Sale Agreement dated as of July 24, 2015, as amended, with Orion Buying Corp. The property sale was previously approved by the limited partners at the special meeting held on November 23, 2015.

Following the closing of the sale, the limited partners and Del Taco LLC (the “General Partner”) will receive a final operating distribution through the closing date and the General Partner will then proceed to dissolve and wind-up the Partnership’s affairs and distribute its net assets (net of costs and dissolution expenses) to the limited partners and General Partner in accordance with applicable law and the Partnership Agreement, which will result in a separate final liquidating distribution to the limited partners and the General Partner. Promptly after that is completed, as required by the Partnership Agreement, the General Partner will file a certificate of cancellation with the California Secretary of State. The General Partner will also terminate the Partnership’s registration under Section 12(g) of the Securities Exchange Act of 1934. As a result of terminating registration under the Exchange Act, the Partnership will no longer file periodic reports with the Securities and Exchange Commission. After the limited partners receive their final liquidating distributions, they will no longer have any continuing interest in the Partnership.
