I've seen Gov't Mule and MMJ there, and it was a wide-open floor, in an old-style theatre (sloped floor and all). I don't think there's a balcony, or if there is, it wasn't in use for the shows I saw there. The bar service when I've been there has been horribly slow, and there may even have been a show where you could buy a beer at the bar in the lobby, but not bring it inside into the music room. (IIRC, Le National is really close to the Voyageur terminal, and the last bus to Ottawa is at midnight. If you ran out of Le National at 11:45pm, you could make it.) Aloha, Brad
