Forgive me if this is old news, as I really didn't have time to read three weeks' worth of blogs while I was away. Looks like while the owners of Smoke Joint have indeed taken over the former Blimpie/Pan-m y Mas space, it won't be an expansion of the restaurant. Instead, it will be a separate market, called Little Piggy (Market). Per TimeOut:
Craig Samuel and Ben Grossman of Brooklyn’s Smoke Joint are back with this Southern country market and café next door to their Fort Greene ’cue house. Pop in for artisanal hams, Anson Mill grits and Greenmarket produce.
A Google search shows some coverage by the Brooklyn Paper as well. The new market will offer both desserts and air conditioning, both lacking at SJ.
Overall, I'm pleased with this. Smoke Joint offers really friendly service and mucho tasty food. Though the SJ is pretty cramped, and it might have been nice to offer more seating.
I peeked inside this morning, and it doesn't seem to be open yet. Also, no sign.
