Flash - Beer Works Lowell is open.
I just had lunch at Beer Works (formerly the Brewery Exchange). I had the "1/2 bowl of chili and 1/2 sandwich of the day" - a chicken club wrap - both excellent.
Their menu looks the same as for the other locations:
They seem to be running in stealth mode at the moment - e.g. no signs up yet. There are tables on the patio, but no umbrellas. They did not quite have a full complement of beers, but I had no problem finding a selection.
