I kind of agree with Beeker. It looks like the fore end of the Port flight deck. From what I remember, Starbuck's "approach" was from the left/port side of the Galactica.
I also agree with AdmiralMcKnight that the flight deck operations look alot like a US carrier. However, when Starbuck / Apollo crashed into the flight deck, I was half expecting to see some kind of safety barrier to "catch" them. I understand that the flight deck was retracted, but still, what a way to stop your forward progress by crashing into a wall.
