Okay, I'm still learning lighting myself (not mention modeling, texturin, skinning, etc), but I think you might be able use point lights for the recessed lighting above the bar area and for the flourescent light in main area, either a series of point lights to simulate the length of the bulbs or if you want that rectangular cast, maybe an area light. I think the secret is going to be more lights and lower intensities. I want to see how you go about this, so keep posting.
