I found prices on par with somewhere like New York and here Toronto.
Yeah the skies the limit in how much can pay in some places but figure $10 for lunch or less or more ... and about $20 for dinner or more or less and I had no issues with prices.
I seldom eat breakfast as does much of Japan I found out
but like yourself I hit a Denny`s. I was curious ...
Probably the healthiest Denny`s ever !
and the politest
I was surprised at how many Italian places there were seems very popular. I also hit the McDonalds right by hotel because I had to have a big mac in tokyo, I just had to have it. Tasted the same as where ever ones lives but the presentation was better
