How to find restaurants/ places to eat in Japan?

Have you ever traveled to Japan, and wondered where to eat? No wonder, there's about 600,000 stores in Japan (that's about 10 times more the number of restaurants in California) so even we get confused where to eat. That's when we use gourmet guide websites like the 3 shown below. 

They are CtoC websites, in which registered members would rank and rate restaurants. One of the website can only be rated by real-name facebook accounts, which guarantees the credibility of the rating.

I've tried it myself, but the google-translates are reasonably accurate. Please use them as a guide to find a place to eat in Japan!
