ITEM 1.     SECURITY AND ISSUER.

      This statement on Schedule 13D (this "Statement") relates to the common
stock, $0.01 par value ("Common Stock") of Denny's Corporation, a Delaware
corporation (the "Issuer"). The principal executive office of the Issuer is 203
East Main Street, Spartanburg, South Carolina 29319-0001.

ITEM 2.     IDENTITY AND BACKGROUND.

      (a), (b) and (c) This Statement is being filed by (i) Jason Ader, an
individual; (ii) Hayground Cove Asset Management LLC, a Delaware limited
liability company ("HCAM"); (iii) Hayground Cove Fund Management LLC, a Delaware
limited liability company ("HCFM"); and (iv) Hayground Cove Associates LP, a
Delaware limited partnership ("HCA" and, together with Jason Ader, HCAM and
HCFM, the "Reporting Persons"). Mr. Ader is the sole member of HCAM, which in
turn is the managing member of HCFM. In addition, HCFM serves as general partner
of (i) certain Delaware limited partnership funds and (ii) HCA, an investment
manager that provides investment and advisory services to certain offshore
entities and individually managed accounts (the limited partnership funds,
offshore entities and managed accounts collectively, the "Client Funds"). None
of the Client Funds is deemed to be a reporting person.

      The principal business of each of the Reporting Persons is providing
investment management and advisory services to the Client Funds.

      The principal business address and principal office address of each of the
Reporting Persons is 1370 6th Avenue, New York, New York 10019.

      (d) and (e) During the past five years, none of the Reporting Persons has
been (i) convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which such person
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

      (f) Mr. Ader is a United States citizen.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      Each of the Client Funds has purchased in the aggregate the shares of
Common Stock reported in Item 5, which shares are indirectly beneficially owned
by the Reporting Persons. The aggregate amount of funds required by the Client
Funds to acquire the shares of Common Stock was $19,880,461, net of commissions.
The funds were provided by working capital of each of the Client Funds.

ITEM 4. PURPOSE OF TRANSACTION.

      The Reporting Persons continue to hold the shares of Common Stock by the
Client Funds reported in Item 5 because, in their opinion, such shares are
undervalued by the market at the

                                                              PAGE 7 OF 10 PAGES
present time. The Reporting Persons remain supportive of the efforts, business
initiatives and management of the Issuer.

      The Reporting Persons effected the acquisition of the shares of Common
Stock by the Client Funds reported in Item 5 for investment purposes only.
However, the Reporting Persons intend to closely monitor the Issuer's
performance and may modify their plans in the future.

      Although the Reporting Persons do not have any current plans other than
monitoring the Common Stock of the Issuer, the Reporting Persons may in the
future exercise, or cause to be exercised, any and all of their respective
rights (or the rights of any of the Client Funds) as stockholders of the Issuer
in a manner consistent with their equity interests (or the equity interests of
any of the Client Funds). More specifically, depending on their evaluation of
various factors, including the investment potential of shares of Common Stock,
the Issuer's business prospects and financial position, other developments
concerning the Issuer, the price level and availability of the Common Stock,
available opportunities to acquire or dispose of shares of Common Stock, realize
trading profits or minimize trading losses, conditions in the securities markets
and general economic and industry conditions, reinvestment opportunities and
other factors deemed relevant, the Reporting Persons may take, or cause to be
taken, such actions with respect to their indirect holdings in the Issuer as
they deem appropriate in light of circumstances existing from time to time. Such
actions may include the purchase of additional shares of Common Stock by some or
all of the Client Funds in the open market, through privately negotiated
transactions with third parties or otherwise, or the sale at any time by some or
all of the Client Funds, in the open market, through privately negotiated
transactions with third parties or otherwise, of all or a portion of the shares
now owned or hereafter acquired by any of the Client Funds.

      As of the date of this Statement, except as set forth above, none of the
Reporting Persons has any present plan or intention that would result in or
relate to any of the actions described in this Item 4.

ITEM 5.     INTEREST IN SECURITIES OF THE ISSUER.

4,477,557 shares of Common Stock currently indirectly owned by the Reporting

Issuer, based upon 92,370,470 shares of Common Stock outstanding as of August 1,
2006, as reported by the Issuer in its Quarterly Report on Form 10-Q for the

and 62,822 shares (or 0.07% of outstanding shares) of Common Stock,
