The accompanying financial statements, some of which are unaudited, have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements and should therefore be read in conjunction with the
financial statements and notes thereto contained in the partnership's annual
report on Form 10-K for the year ended December 31, 2000. In the opinion of
management, all adjustments (consisting of normal recurring accruals) necessary
to present fairly the partnership's financial position at June 30, 2001, the
results of operations and cash flows for the six month periods ended June 30,
2001 and 2000 have been included. Operating results for the three and six months
ended June 30, 2001 are not necessarily indicative of the results that may be
expected for the year ending December 31, 2001.

NOTE 2 - NET INCOME PER LIMITED PARTNERSHIP UNIT

Net income per limited partnership unit is based upon the weighted average
number of units outstanding during the periods presented which amounted to
165,375 in 2001 and 2000.

Pursuant to the partnership agreement, annual partnership income or loss is
allocated one percent to the General Partner and 99 percent to the limited
partners. Partnership gains from any sale or refinancing will be allocated one
percent to the General Partner and 99 percent to the limited partners until
allocated gains and profits equal losses, distributions and syndication costs,
and until each class of limited partners receive their priority return as
defined in the partnership agreement. Additional gains will be allocated 12
percent to the General Partner and 88 percent to the limited partners.

NOTE 3 - LEASING ACTIVITIES

The partnership leases certain properties for operation of restaurants to Del
Taco, Inc. on a triple net basis. The leases are for terms of 32 years
commencing with the completion of the restaurant facility located on each
property and require monthly rentals equal to 12 percent of the gross sales of
the restaurants. There is no minimum rental under any of the Leases.

For the three months ended June 30, 2001, the two restaurants operated by Del
Taco, for which the partnership is the lessor, had combined, unaudited sales of
$453,954 and net income of $30,663 as compared to $440,807 and $29,700,
respectively, for the corresponding period in 2000. Net income by restaurant
includes charges for general and administrative expenses incurred in connection
with supervision of restaurant operations and interest. For the three months
ended June 30, 2001, the one restaurant operated by a Del Taco franchisee, for
which the partnership is the lessor, had unaudited sales of $287,369 as compared
with $263,968 during the same period in 2000.

For the six months ended June 30, 2001, the two restaurants operated by Del
Taco, for which the partnership is the lessor, had combined, unaudited sales of
$871,766 and net income of $54,513 as compared to $857,911 and $53,903,
respectively, for the corresponding period in 2000. For the six months ended
June 30, 2001, the one restaurant operated by a Del Taco franchisee, for which
the partnership is the lessor, had unaudited sales of $546,457 as compared with
$498,058 during the same period in 2000.

NOTE 4 - TRANSACTIONS WITH DEL TACO

The receivable from the General Partner consists primarily of rent accrued for
the month of June. The June rent was collected on July 10, 2001.

Del Taco, Inc. serves in the capacity of general partner in other partnerships
which are engaged in the business of operating restaurants, and three other
partnerships which were formed for the purpose of acquiring real property in
California for construction of Mexican-American restaurants for lease under
long-term agreements to Del Taco, Inc. for operation under the Del Taco trade
name.

In addition, see Note 5 with respect to certain distributions to the General
Partner.

NOTE 5 - DISTRIBUTIONS

On July 18, 2001, a distribution to the limited partners of $72,050 or
approximately $.44 per limited partnership unit, was approved. Such distribution
was paid July 20, 2001. The General Partner also received a distribution of $728
with respect to its 1% partnership interest.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

Liquidity and Capital Resources

The partnership offered limited partnership units for sale between June 1987 and
June 1988. 14.5% of the $4.135 million raised through sale of limited
partnership units was used to pay commissions to brokers and to reimburse the
General Partner for offering costs incurred. Approximately $3 million of the
remaining funds were used to acquire sites and build three restaurants. In
February of 1992, approximately $442,000 raised during the offering but not
required to acquire sites and build restaurants was distributed to the limited
partners.

The three restaurants leased to Del Taco make up almost all of the income
producing assets of the partnership. Therefore, the business of the partnership
is almost entirely dependent on the success of the Del Taco trade name
restaurants that lease the properties. The success of the restaurants is
dependent on a large variety of factors, including, but not limited to, consumer
demand and preference for fast food, in general, and for Mexican-American food
in particular.


Results of Operations

The partnership owns three properties that are under long-term lease to Del Taco
for restaurant operations (Del Taco, in turn, has sub-leased one of the
restaurants to a Del Taco franchisee).

The following table sets forth rental revenue earned by restaurant for the three
and six months ended June 30, 2001 and 2000:

The partnership receives rental revenues equal to 12 percent of gross sales from
the restaurants. The partnership earned rental revenue of $88,959 during the
three month period ended June 30, 2001, which represents an increase of $4,386
from 2000. The partnership earned rental revenue of $170,187 during the six
month period ended June 30, 2001, which represents an increase of $7,471 from
2000. The changes in rental revenue between 2001 and 2000 are directly
attributable to changes in sales levels at the restaurants under lease.

General and administrative costs for the six month period ended June 30,
increased from 2000 to 2001 due to increased costs for income tax preparation
and annual audit fees. Depreciation decreased in 2001 because certain equipment
became fully depreciated during 2000.

For the three month period ended June 30, 2001, net income increased by $2,135
from 2000 to 2001 due to the increase in revenues of $4,028 which was partially
offset by the $1,893 increase in general and administrative expenses. For the
six month period ended June 30, 2001, net income increased by $8,891 from 2000
to 2001 due to an increase in revenues of $7,330 and a decrease in depreciation
expense of $4,217 which was partially offset by an increase in general and
administrative expenses of $2,656.

In accordance with recent U.S. Government regulations, the partnership is
required to file annual K-1 income tax forms with the Internal Revenue Service
electronically beginning in 2002 for the year ending December 31, 2001. In order
to comply with this regulation, the partnership will incur additional costs to
lease software to 1) prepare the tax forms electronically and 2) maintain the
underlying partnership database.

The General Partner and outside consultants are evaluating available software
and expect to select a software package in the third calendar quarter of 2001.
Estimates of additional general and administrative costs to lease the software
range from $1,000 to $2,000 in 2001 (the conversion year) and range from $1,000
to $2,000 in each subsequent year.
