I was totally floored and impressed with the layout here but keep in mind I was there at 2pm amongst 3 other patrons so I can envision it being a different feel if congested and busy. Its almost set up like you are stepping into the trunk of a giant pine tree with what i would call 1.5 floors/levels since each isn't actually much different height than the other but there is a small difference. The bottom one is a few vending machines along with small tables. The middle level was the main bar although small gives a person an interesting viewpoint of the other 2 levels. And at the top level were the dart boards and pool tables. I didn't use the restroom facilities.
I liked how they offer Molson on tap as I rarely see this brew in Pittsburgh anymore and prices for a tall one were reasonable the best yet the mug was iced :)
