Brooklyn Record is just a treasure trove of good Brooklyn events. Check this out:

The Transit Museum presents The L to the MMMMM Train.  Saveur
food editor Todd Coleman, a guy who really knows his stuff, will lead a
tour along the L and M lines to some of the best ethnic eateries in
Brooklyn and Queens. On this journey, you can expect to:

"Visit an ancient Sicilian dolceria for crisp-shelled cannoli. Warm your belly Puebla-style with a hot cup of creamy atole de arroz at a Mexican emporium of cookware, hard-to-find comestibles, and antojitos.
Shop for thick ropes of garlicky kielbasa, feast in a taqueria located
in a humming tortilleria where the tortillas are hot off the press, and
finish up among the steins and schnitzels in the vestiges of old German
New York. Wear comfortable shoes and loose clothing, as there will be a
good amount of walking and eating!
