Seen lots since arriving, due to my good lady's many friends and her ability to arrange comps for us! Saw 'The Herd' by Rory Kinnear on the Steppenwolf main stage - it's a belter of a space. 'Doubt: A Parable' is a tightly written piece performed up in a church in Glencoe and put on by Writer's Theatre. Cheers Mitch for that one.
'Store front' is the sort of intimate, black box theatre that Chicago is well-known for. My favourites so far: 'Goldfish' (Route 66) - cracking central performances by Fran Guinan and Tyler Meredith; and 'Abraham Lincoln Was a F*gg*t' (AboutFace), a charming and playful wee show with the music of Michael Jackson underscoring it all. The Edinburgh Festival would eat it up - I sincerely hope they take it there.
