I remember I was in Roppongi Hills and saw 2 pcs Goyoza for 800 yen. Needless to say, I didn't eat anything while I was there.
In Kyoto, some famous tofu resturant. I think this was a 20,000 yen meal. Not a single piece of meat.
I usually ate at the cheaper places where 800-900 yen can get you something like this
Or when I was really hungry and feeling cheap. I'd eat 2 of these for 300-400 yen
