Umbrella Birds

Set and staged in a portable toilet, this series of vignettes veers from the clownishly comical to awkward and tender. Acutely observed and excellently acted by its four-strong female cast, it never takes the easy route to laughs and allows each scene to play out to a natural conclusion. There are only eight seats, so book tickets quickly for the most enjoyable hour you will spend in a toilet this year (Gordon Eldrett)
