A is not for "apartment house" with a commercial tenant tucked in the prow; A is for "Aztec architecture" enlivened by a chile-pepper apostrophe. As you've guessed, the deli counter focuses on Mexican fare. (A supplemental menu offers Dominican lunch specials, also prepared by an able hand; shards of concon, hidden behind the counter, await those who know to ask.) The edifice of my torta de lengua con todo ($7), a beef tongue sandwich with the works, was demolished in short order.
