Here is a topic to discuss openings and closings in the Boston Area split by month as proposed since past seasonal topics were getting very long. We will have to see whether this new format works as many restaurant openings when they are close take more than a month, heck even waiting for the fire marshall seems to take longer than that sometimes. :-) If discussion of a opening continues to another month, you can use the "permalink" feature to link back previous discussions to be helpful to other hounds. As a reminder, restaurant reviews should be put into a separate new topic.
East by Northeast seems pretty far along, so I'll put that as a maybe for January. Sounds like Ebisuya is another strong possibility (and the fire marshall could walk there!). The new Muqueca and maybe the Cambridge Floating Rock (is there any work going on the "proposed" location) seem a bit further out, but I bet the former could be a winter opening.
I noticed Poboys on 3rd Street in Everett which I think could be a new or (re)opening (there was something always closed in that location, but today it was fully stocked, had some new equipment, and brand new menus on the door). It was closed today either as Saturday or a snow day, but since they were advertising "all subs $3.99" I am guessing that seafood Po'Boys probably are not their specialty but something to find out more later.
