Beer, the perfect, final touch, has been added to the Flea Food Under the Archway program, which also includes Asia Dog, Mile End, Brooklyn Oyster Party, and Landhaus. But plan wisely: the Flea team will only be serving beer for the next four Thursdays (July 19 and 26 and August 2 and 9) between 3 p.m. and 9 p.m.
