11. Rubio’s Fresh Mexican Grill
Carlsbad, Calif. / No. of units: 203
Rubio’s Fresh Mexican Grill, famous for its Baja-style fish tacos and other seafood specialties, proves that going green can be profitable. Known for its beach cleanup efforts, environmentally efficient store design and eco-friendly packaging, the company, having ended its first 2010 quarter with no debt and $8.3 million in cash, was acquired last year by private-equity firm Mill Road Capital LP for $91 million — or about 14 percent more per share than the company’s stock price at the time of the agreement.
