Updated: El Carnaval opened on May 9!
We're told the new venture is from the folks who run KC Gourmet Empanadas right next door...
... that space looks to become a to-go outpost for El Carnaval...
Fonda, the previous tenant at 40 Avenue B, closed last summer. The Mexican restaurant's other locations in Chelsea and Park Slope remain open. This outpost opened in February 2012, stopping the revolving door of restaurants to come and go here.
Thanks to Stacie Joy for the photos and Vinny & O for the tip!
