I saw something like this before, and they are usually two businesses with different names. I used two separated POIs (points) placed in the same building area to denote them. In this way, I can also put different names, opening_hours etc to the two POIs.
In the case of the café/bar, they are distinctly the same place. It's actually something I've run across several times in different places, usually they're more upscale than your typical café. Pretty good venue for a date that you're not sure how long you want it to last!
