The Acorn Theater is housed in a turn of the century former corset stay factory. (The factory's conversion to performance space was the subject of recent multiple shows on HGTV.) Make sure to take a look at the 1931 Barton theater pipe organ while you're there.
The 250-seat space hosts high-quality professional performances and live theater. They produce approximately 45 separate shows yearly, with very diverse offerings. Shows most Friday and Saturday evenings--check web site for current show schedule and details.
