Chicago,  IL. May 4, 2006...  Morton's  Restaurant Group, Inc.  (NYSE:MRT) today
reported  unaudited  financial  results for its 2006 fiscal first  quarter ended
April 2, 2006.

"The strength of our Morton's brand and our business  model is clearly  evident"
said Thomas J.  Baldwin,  Chairman,  Chief  Executive  Officer and  President of
Morton's   Restaurant  Group,  Inc.  "We  are  happy  to  report  first  quarter
record-setting  revenues of $83.1  million and the opening of our 70th  Morton's
Steakhouse, in Troy, Michigan."

"We have a clear and  focused  strategy,  including  a  disciplined  approach to
developing new  restaurants  and expanding our Boardroom  private dining and Bar
12-21  businesses.  We are  continually  committed to our Morton's  standards of
providing  the highest  quality  guest  experience  levels in the  industry," he
added.

FIRST  QUARTER OF FISCAL 2006 RESULTS
Revenues for the first  quarter of fiscal 2006  increased  7.4% to $83.1 million
from $77.3 million for the first quarter of fiscal 2005.  The growth in revenues
is attributable to a 4.4% increase in comparable  restaurant  revenues (13 weeks
to 13 weeks) and revenues from four new Morton's steakhouse  restaurants,  which
opened in fiscal 2005, and one new Morton's steakhouse restaurant,  which opened
in March 2006.  The Company  believes that Morton's 2006 first quarter  revenues
were favorably impacted by an April 2006 Easter versus March 2005.

Management  fee paid to related  party was $0.4 million for the first quarter of
fiscal 2006,  compared to $0.7 million in the first quarter of fiscal 2005.  The
related management agreement was terminated in connection with the Company's IPO
in February  2006 and the  Company  incurred an $8.4  million  termination  fee.
(Refer to the  reconciliation  of pro forma net income to GAAP net income (loss)
in the financial tables that follow.)

In connection with the IPO, during the first quarter of fiscal 2006, the Company
incurred  costs  associated  with debt  repayment  of $28.0  million,  primarily
consisting of prepayment  penalties that were incurred with the early  repayment
of the 7.5% senior secured notes and the 14.0% senior  secured  notes.  The debt
was refinanced in conjunction with the Company's IPO. Costs associated with debt
repayment  of $0.2  million  for the  three  month  period  ended  April 3, 2005
represents  prepayment  penalties that were incurred with the early repayment of
certain mortgages.  (Refer to the reconciliation of pro forma net income to GAAP
net income (loss) in the financial tables that follow.)





Interest  expense,  net was $2.2  million  for the first  quarter of fiscal 2006
compared to $4.3 million in the first  quarter of fiscal  2005.  The decrease is
due to the  repayment,  in connection  with the IPO, of the 7.5% senior  secured
notes and the 14% senior secured notes partially offset by the interest relating
to  borrowings   under  our  new  revolving   credit   facility  (Refer  to  the
reconciliation  of pro  forma  net  income  to GAAP  net  income  (loss)  in the
financial tables that follow).

The Company's pro forma net income was $5.4 million,  or $0.32 per diluted share
for the first  quarter of fiscal 2006,  compared to pro forma net income of $4.1
million, or $0.24 per diluted share, for the first quarter of fiscal 2005 (refer
to the  reconciliation  of pro forma net income to GAAP net income (loss) in the
financial tables that follow).

RESTAURANT DEVELOPMENT
On March 29, 2006, the Company opened a Morton's steakhouse  restaurant in Troy,
MI. The Company has executed leases to open new Morton's steakhouse  restaurants
in Anaheim, CA; Coral Gables, FL; Houston, TX; Northbrook, IL and San Jose, CA.

SECOND QUARTER 2006 AND FULL YEAR 2006 FINANCIAL GUIDANCE
The Company  expects  second  quarter 2006 revenues to range between $76 million
and $77 million including increases in comparable restaurant revenues between 2%
to 3%. Diluted net income per share is expected to  approximate  $0.14 to $0.15.
This range  includes  estimated  compensation  expense  pursuant to Statement of
Financial  Accounting  Standards No. 123R "Share Based Payment" (SFAS No. 123R),
which requires the expensing of stock issued to employees  (approximately  $0.01
per diluted share).

The Company  expects  fiscal year 2006  revenues to be between  $313 million and
$318  million  including   increases  in  comparable   restaurant   revenues  of
approximately  2% to 3%. Excluding all  non-recurring  items associated with the
IPO and other  costs  associated  with the  early  retirement  of debt,  pre-IPO
management   fees,   management   termination   contract  costs,   the  one-time
compensation  expense  attributable  to  the  vesting  of  the  executive  units
previously  granted to certain  employees and adjusting the interest expense for
the pro forma effects of the change in the debt structure, pro forma diluted net
income per share is expected to be between $0.74 and $0.77.  This range includes
estimated  compensation  expense pursuant to SFAS No. 123R (approximately  $0.03
per diluted share). This range includes expectations that the Company's 2006 pro
forma income tax rate  approximates 32% to 34%. The Company expects to open four
to five new Morton's steakhouses in fiscal 2006.
