On the first level, there is a ground floor, behind the soundboard are tables with chairs which usually sell out quick. Second level their are steep theater seats. It's actually quite small and intimate. They used to let you stand behind the soundboard but after adding the extra tables and seats, they pack everyone else on the ground floor like a concentration camp. If you catch the Insomniac Tour special on comedy central, it was filmed in there and they make it look a hundred times bigger than it really is.
Saw Opeth here in Vegas when they last toured with Megadeth during Gigantour. They played four songs then left. Then I sat through that Lamb of God shit and Megadeth, very heart broken.
