looks like some of these restaurants are merged on to the building part areas here but they should probably be separated into their own areas if representing an indoor space as the current room tag suggests. The restaurant does not occupy the entire building part and it wouldnt make sense that the restaurant has 40 levels. I suggest disentangling the pois that are rooms from the building parts and making each have their own distinct areas: one for the building part and levels and one for the restaurant. Example of one that could be updated but there are others: https://www.openstreetmap.org/way/115661799
