is this raceway name known? if so it would be useful to add it or a area for the venue

seems like station tagging is not quite right here, there are 3 nodes tagged as stations but only one should be tagged as such. Perhaps relation and station parts need to be updated? Looks like multiple stations on D line have this same issue. Example for this station: way/784708488, way/784708489, node/13807935230

hotels in area have a number of duplicate hotel tags as an area for entire hotel area but with no information in them and then also a hotel tag on the buildings, suggest tagging the areas with all the hotel tags and the buildings with just the building=hotel tag and related name or addr info

looks like the cinema here is represented twice: one as a node and one as an area, suggest only using one to remove duplicate information. In addition, there are overlapping buildings in this retail area.

these are all separate structures here not one large building, suggest adding separate building areas for each structure instead

suggest placing the tourism=hotel tags that are on the building here on to the tourism=hotel area here and then removing the hotel tags from the building but leaving building=hotel and addr info. This would help reduce duplicate information.

there are a lot of duplicate "United Talent Agency" office pois in this area (about 11 or so), it seems even though the buildings have different addresses, the office pois could be consolidated into a single area or something to reduce the amount of duplicate information...

this poi sounds like it may be a school and not a hospital, verification is needed

river should be extended

rd needs to be verified if it continues and connects to east 2nd street
