I'm reminded of some stat (which I haven't verified) that there were ~15k tripadvisor restaurants in London (a "large" city). There were 65k for Hong Kong... Tokyo had 80k

Granted, Tokyo is very large. I got a bit burned out in my first two trips because hauling from one side to the other constantly to hit different sites is kind of exhausting but yes as another comment mentioned - it's totally normal to find restaurants on floors 1 through 10+++ so you can stack a lot of restaurants vertically. Within the city I was told not many people cook and a friend living there told us a lot of apartments don't even have a kitchen beyond a tiny heater for cooking instant noodles or simple stuff.
