Just figured I'd start this thread, since it's no longer spring. ;-b
I'll start with a few (most of which have already been mentioned):
Max & Dylan's in Boston, Stone Hearth Pizza in Cambridge, BurgerWorks in Beverly, Roadhouse BBQ in Brookline, and T-Rex Taqueria, also in Brookline, are open.
Sabor Do Brasil in Somerville, Aneka Rasa in Allston, and Eastern Pier in the Seaport District are all closed.
