I have to say that scrambled egg and bacon ice cream would have me vomiting and feeling ill even in the absence of any food-borne pathogen.

I think some of the disagreement here has to do with WHERE the diner is eating rather than what and how much. If one frequents Robuchon and Ramsey's places, one will pay through the nose. Saying that Japan is expensive for dining based on that sample is misleading. The best meals I have ever had were at no-name back-street places (like the "Cafe Macaroni" in the dorama "Lunch Queen"). A tonkatsu, hayashi rice or curry lunch special almost never runs more than 800 to 1200 yen and rarely fails to satisfy completely. Really good ramen or soba at the local noodle joint is always good and usually runs 500-800 yen. I can't eat that well for that little money at home.
