ITEM 8.01   OTHER EVENTS.

            On May 11, 2007, Riviera Holdings Corporation (the "Company") issued
a press release  announcing  that the Company has retained  Jefferies & Company,
Inc. as its financial advisor to assist it in exploring a range of strategic and
financial  alternatives  in order to enhance  shareholder  value (the  "Jeffries
Release").  These  alternatives  include,  but are not limited to, a sale of the
entire Company.

      A copy of the Jeffries Release is filed as Exhibit 99.1 to this Form 8-K.

     In addition,  on May 11, 2007,  the Company  issued a second press  release
(the "Eichner Release"),  announcing that the Company had received a bid for $30
per  share in cash  from a group  led by Ian  Bruce  Eichner  and  Dune  Capital
Management LP (the "Eichner  Group").  The Eichner Group's bid represents an 11%
premium  over a  competing  bid at $27 per share that had been  received  by the
Company from a dissident  investor group led by Riv  Acquisition  Holdings.  The
Company  stated that it believes the $27 per share offer does not represent full
value for its  stockholders,  as confirmed by both the Company's  current market
price  ($31.85 close on May 10, 2007) as well as the current $30 per share offer
from the Eichner  Group.  The Company  further  stated that the Board intends to
fully  consider the $30 Eichner Group bid and review it with Jeffries & Company,
Inc. its financial advisor.

      A copy of the Eichner Release is filed as Exhibit 99.2 to this Form 8-K.
