I went here for the James Blunt concert earlier this year. Pretty lovely theatre, seats are comfortable and nicely spaced out. I sat in the orchestra seating, so we were pretty close. The staff there were pretty accommodating. I can't really say anything bad about my experience.
Except maybe the price of the snacks there. It's a classy joint, they sell wine, by the glass... hmmmmmm...
Parking is a bitch there.. there's a lot of underground parking that's cheap after 6pm, and of course green P parking is free after 9pm.
