Speaking of wintry food... A new pierogi restaurant called Stuffed is making its way to the small shop space that currently houses Mission Sub (2788 Mission between 23rd and 24th). Grub Street catches the news this a.m. and some further digging reveals that owners Dana Sacco and Andy Schoengrund have been developing their pierogi bar concept for a number of months now. We've reached out for some further details and an opening timeframe (it will obviously be 2013) and will let you know as soon as we know more. For now, as far as we can tell, Mission Sub remains open. Update: As the owners of nearby Wise Sons Deli joke via Twitter, "It's becoming a 24th Street shtetl." Update 2: Sacco reaches out to say that they're aiming for a mid- to late-January opening after a brief remodel, and among the types of pierogis served will be a traditional pierogi with potato, farmer's cheese, and cheddar cheese and optional bacon wrapping; a pulled pork pierogi with walnut butter sauce and fontina cheese; and a spicy Buffalo pierogi with potato and blue cheese, pan fried in spicy Buffalo sauce. Here's the menu.
