hey, it looks excellent, love ya work.... i like the talking alcohol tester on the bar, bet it gets a workout. i notice the lock on the alcohol fridge 
regarding your question re the roof, yeh, why not put some random playfields up there, maybe add a few inexpensive rope lights for max effect of a nightime. but it looks great and i am impressed with the variety you have. 
ohh, the blacklight glowing barfridge is awesome.
Ive blown the ass out of the alcohol tester i think it needs a new sensor LOL.
Its hard to tell in the photos but i have a Disco UFO light up one end and the chasing lights on one side wall so rope lights would look pretty cool. But once all the machines and signs are turned on its like daytime lol.
And for the sake of the pinnies i didnt put in any sky light or windows to try and avoid as much fading as possible
