Rubin'sn Kosher Restaurant Delicatessen

Yarmulke-bedecked customers attest to the kosher bona fides at this Brookline mainstay, where the takeout case is long and complete, the sandwiches are overstuffed with choice cuts, and the pickles—well, Rubin's knows from pickles, offered free in the tightly packed dining room. And you can bet your tuches that Bubbe would approve of the meat knish: flaky crust setting off pillowy mashed potato and salty ground beef, the whole mess served piping hot.
