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, 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");  and (iii)  Hayground Cove Fund  Management LLC, a
Delaware  limited  liability  company ("HCFM" and,  together with Jason Ader and
HCAM, 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)  Hayground  Cove
Associates LP, a Delaware limited  partnership  ("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 HCA or 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 $21,198,423, 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 6 of 8 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
4,648,700, shares of Common Stock  currently  indirectly  owned by the Reporting
Persons,  or  approximately  5.1% of  outstanding  shares of Common Stock of the
Issuer,  based upon 90,687,506  shares of Common Stock  outstanding as of May 3,
2005,  as  reported by the Issuer in its  Quarterly  Report on Form 10-Q for the
quarter  ended March 30,  2005.  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  may be  deemed to share  indirect
beneficial  ownership of the shares of Common Stock directly  beneficially owned
by the  Client  Funds.  Specifically,  as  general  partner,  HCFM has  indirect
beneficial  ownership of (i) 433,700 shares (or 0.48% of outstanding  shares) of
Common  Stock held  directly by  Hayground  Cove  Institutional  Partners  LP, a
Delaware 





                                                               Page 7 of 8 Pages


limited partnership, and (ii) 346,700 shares (or 0.38% of outstanding shares) of
Common Stock held directly by Hayground  Cove Turbo 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) 2,431,750 shares (or 2.68% of outstanding shares)
of Common Stock held directly by Hayground Cove Overseas Partners Ltd., a Cayman
Islands exempted  limited company;  (ii) 490,050 shares (or 0.54% of outstanding
shares) of Common  Stock held  directly  by  Hayground  Cove Turbo Fund Ltd.,  a
Cayman Islands exempted limited company;  and (iii) certain  independent managed
accounts,  each of which  directly owns 249,100  shares (or 0.27% of outstanding
shares) of Common  Stock,  562,350  shares (or 0.62% of  outstanding  shares) of
Common Stock and 135,050  shares  directly (or 0.15% of  outstanding  shares) of
Common Stock, respectively.

     (b) Each of the  Reporting  Persons 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- 
         (ii)  Shared power to vote or to direct the vote: 4,648,700 
         (iii) Sole power to dispose or to direct the disposition of: -0- 
         (iv)  Shared power to dispose or to direct the disposition
               of: 4,648,700

     (c) The  Reporting  Persons have caused the purchase by the Client Funds of
903,655  shares of Common Stock within the last 60 days with a range of purchase
prices  between  $3.650 and $4.945.  All such  purchases  were effected  through
over-the-counter bulletin board transactions.

     (d)  Except as stated  elsewhere  in this Item 5, no other  person  has the
right to receive or the power to direct the receipt of  dividends  from,  or the
proceeds  from the sale of, the shares of Common Stock  indirectly  owned by the
Reporting Persons.

     (e) Not applicable.

Item 6.     Contracts, Arrangements, Understandings or Relationships With 
Respect to Securities of the Issuer.

     Other than as  described in Items 2 and 5 of this  Statement,  there are no
contracts,  arrangements,  understandings or relationships  (legal or otherwise)
among the  Reporting  Persons  named in Item 2 and between  such persons and any
person with respect to any  securities of the Issuer,  including but not limited
to transfer or voting of any of the securities,  finder's fees,  joint ventures,
loan or option arrangements,  puts or calls, guarantees of profits,  division of
profits or loss, or the giving or withholding of proxies.

Item 7.     Material to be Filed as Exhibits.

Exhibit A   Joint Filing Agreement Among the Reporting Persons.
