Karate Academy offers classes a couple of nights a week, although I can't comment on the quality.  I think they start at 9:00pm, but not sure of the days.

There is also a small group that rents the Karate Academy dojo every Friday at 1:30pm for Aikido training offered by Siyavush Sensei.  Siyavush is sandan (3rd dan)...good class.
