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 $25,534,742, net of commissions.
The funds were provided by working capital of each of the Client Funds.

ITEM 4. PURPOSE OF TRANSACTION.

        The Reporting Persons have effected the purchase of the shares of Common
Stock  by the  Client  Funds  reported  in  Item 5 in open  market  transactions
because,  in their  opinion,  such shares are  undervalued  by the market at the
present time.




                                                             PAGE 7 OF 10 PAGES


        The Reporting  Persons believe that the addition of the shares of Common
Stock of the Issuer in the  accounts  of the Client  Funds is a strong  positive
development. In particular, the Reporting Persons are supportive of the efforts,
business initiatives and management of the Issuer.

        The  Reporting  Persons have 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.

        (a) In the aggregate,  the Client Funds are the direct beneficial owners
of 5,612,200 shares of Common Stock currently  indirectly owned by the Reporting
Persons,  or  approximately  6.08% of outstanding  shares of Common Stock of the
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
quarter ended June 28, 2006. None of the Client Funds own individually in excess
of five percent of the outstanding shares of Common Stock.

        By virtue of the relationships described in Item 2 of this Statement and
this Item 5, each of the  Reporting  Persons  (other  than HCA) may be deemed to
share  indirect  beneficial  ownership  of all of the  shares  of  Common  Stock
directly  beneficially  owned by the  Client  Funds.  HCA may be deemed to share
indirect  beneficial  ownership of the shares of Common  Stock as expressly  set
forth below.  Specifically,  as general  partner,  HCFM has indirect  beneficial






                                                             PAGE 8 OF 10 PAGES

partnership,  and (iii) 80,925 shares (or 0.09% of outstanding shares) of Common
Stock held directly by Hayground  Cove Equity Market Neutral Fund LP, a Delaware
limited partnership.  In addition, HCFM is general partner of HCA, which in turn
serves  as  investment  manager  pursuant  to  certain   Investment   Management
Agreements entered into between HCA and certain individual Client Funds. In this
capacity, HCA exercises the power to vote (or to direct the vote) and to dispose
(or to direct the disposition of) (i) 2,622,907  shares (or 2.84% of outstanding
shares) of Common Stock held directly by Hayground Cove Overseas  Partners Ltd.,
a Cayman  Islands  exempted  limited  company;  (ii) 371,208 shares (or 0.40% of
outstanding  shares) of Common Stock held directly by Hayground  Cove Turbo Fund
Ltd., a Cayman Islands exempted  limited company;  (iii) 49,925 shares (or 0.05%
of  outstanding  shares) of Common Stock held directly by Hayground  Cove Equity
Market Neutral Fund Ltd., a Cayman Islands exempted  limited  company;  and (iv)
certain independent managed accounts, each of which directly owns 624,025 shares
(or 0.68% of  outstanding  shares) of Common Stock,  363,359 shares (or 0.39% of
outstanding  shares) of Common Stock,  576,143  shares (or 0.62% of  outstanding
shares) of Common Stock and 74,022  shares (or 0.08% of  outstanding  shares) of
Common Stock, respectively.

        (b) Each of the Reporting Persons (other than HCA) has the power to vote
and to dispose of shares of Common Stock as follows:

            (i)    Sole  power  to vote or to  direct  the  vote:  -0-
