uuhhh, do musicals count???
I go to the local Shakespeare in the Park if the weather isn't too hot here (Dallas). "Much ado about Nothing" and "A midsummer's night dream" along with the the "M" Play you mentioned. Have never seen, but have read "The Tempest"...my favorite Shakespeare play of all.
Any Neil Simon play will catch my eye (old school, I know).
Recently, I've enjoyed the musicals...last year in London "Wicked", and "We Will Rock You"...
"South Pacific" most recently at the new opera house in Dallas. When in Vienna, I go to the opera as often as possible...maybe more my speed.
BTW, I will be moving to London ( most likely North) in May, and I will take full advantage of the theatre while I'm there. So Camille, any suggestions are welcomed as well.
