Is this really the bar in Van Gogh's painting?

Yes, that's the place, but it would not necessarily have been yellow at the time Van Gogh painted it. The yellow in his painting is his interpretation of the color thrown by the caf�'s artificial lighting at nighttime, not the actual color of the building. I think the old caf� was renovated in the early 1990's to look more like the painting, and it may have been painted yellow at that time.
