I like how everything is organized! For the header area, I find it a bit plain. What I would do is use a solid background color behind your logo text and change your logo text to a gradient white. Faded images in the background would also make it less plain.
yeah it is pretty clean for an arcade which is pretty good. Maybe try not having red bars behind the categories in the middle, because it makes it harder to browse and somewhat distracts from the games. If all the tables that the games are in were different sizes, browsing may be a bit easier as well.
I just recently saw this template for sale.....I like it but it's not unique. Good luck with it though.
