The only Polish restaurant currently in business in Pittsburgh is the Bloomfield Bridge cafe, located right at the Bloomfield side of the Bloomfield Bridge. Their food is reasonably good. Also, for great pierogis, try the Byzantine Rite Church of the Nativity on Friday afternoons. It is located on Beechwood Blvd. in Greenfield, near the bridge that crossses over the Parkway from Schenley Park. It is strictly take-out, and eventough the church is Carpatho-Ruthenian rather than Polish, their various varieties of pierogi are FANTASTIC!!
