                RUBIO'S(R) REPORTS 1.6% INCREASE IN Q1 COMPARABLE
                        STORE SALES AND MEETS Q1 GUIDANCE

CARLSBAD, CA - May 8, 2003 - Rubio's Restaurants, Inc. (Nasdaq: RUBO) today
announced that revenues of $30.5 million for the 13 weeks ended March 30, 2003
increased 2% over revenues of $29.9 million for the same period last year.
Comparable store sales increased 1.6% over the same period a year ago, which is
within the comparable store sales guidance of 1% to 2%, released in mid-March.
"We were very pleased to post positive comparable sales in Q1, particularly
during a time of political and economic uncertainty and when many
restaurant/retail companies posted same store sales declines," said Sheri Miksa,
president of Rubio's. "These positive comp sales trends are evidence that our
"Evolution" strategy continues to strengthen our overall business. The Evolution
initiative provides larger portions, more grilled chicken, steak and
HealthMex(R) items and our new roasted chipotle salsa."

The company also announced net income of $56,000, or $0.01 per share for the 13
weeks ended March 30, 2003, compared to net income of $427,000 or $0.05 per
share for the same period a year ago. The earnings per share of $0.01 is within
the company's previous guidance of $0.01-$0.03 range previously announced on
March 12, 2003. "While the comp sales trends were positive, they were not as
strong as we had anticipated and we believe the shortfall was primarily due to
three factors: slowdown in retail activity, rollovers of previous deep-discount
promotions and poor weather in California (rain) and in the mountain states,"
said Miksa. "In addition, we had a number of planned one-time charges during the
quarter related to our Evolution initiative and our company-wide reorganization.
These primary factors had a larger impact on overall profitability due to softer
sales earlier in the quarter. Despite these impacts, our quarterly EPS was
within the projected range. Our strategy was to complete the Evolution
investments early in the year to obtain the maximum sales benefit for as much of
the fiscal year as possible. From this improved operational and competitive
foundation, we can now continue our focus on building sales with our new
marketing campaign, initially featuring our $5.99 Fajita Fiesta on television
and radio."

The company opened two new restaurants during the first quarter, one in
Escondido, California (San Diego area) and one in Emeryville, California (San
Francisco/Oakland area). The company expects to open an additional six to eight
company-owned restaurants this year, utilizing their new prototype design,
introduced in Q4 of 2002.
