Another survivor from the old East Village bites the dust. It’s last call this Sunday at longtime neighborhood pub Dempsey’s, which opened nearly a quarter-century ago as an Irish bar and became a popular hangout for local college students. Owner Tom O’Byrne, who also owns the beer-centric Cooper’s Craft and Kitchen nearby, unsurprisingly tells Bedford + Bowery that neighborhood changes are partly to blame for the closure. Dive bars continue to vanish from downtown, with Meatpacking District classic Hogs & Heifers shut down last year, Puck Fair closed in March, and Tribeca’s Raccoon Lodge not long for this world. If, like so many others, you mourn these losses, Dempsey’s has an all-day happy hour through Sunday ($5 beer, wine, and well drinks), and O’Byrne promises canned- and bottled-beer specials on Sunday night.
