This gleaming, mirror-walled, glass-enclosed cylinder seats 2,743 and the acoustics are phenomenal. If the minimalist look of the Louise M. Davies Symphony Hall is somewhat disquieting, given the Beaux Arts look of the rest of the San Francisco War Memorial & Performing Arts Center, never mind. Like the symphony itself, the 9,000 pipes of the Ruffati organ that looms behind the stage makes quite a statement.
