Dos Toros. Open for a few months. Best burrito in the city. Lines can be crazy since the NY Times reviewed it a few weeks ago: <a href="http://events.nytimes.com/2010/01/06/dining/reviews/06unde.html" rel="nofollow">http://events.nytimes.com/2010/01/06/dining/reviews/06unde.h...</a><p><i>IF the Dos Toros Taqueria just off Union Square brings to mind the sort of fresh, quick and cheap eating found at Mexican joints in the San Francisco Bay Area, that’s by design.<p>It was opened by Leo and Oliver Kremer, brothers from Berkeley, Calif., who worshiped Gordo Taqueria, a Bay Area favorite founded in 1977. Dos Toros is something of an homage.</i>
