For people who are interested in this sort of thing.
It seems like michelin three stars are, on average, significantly favored on tabelog over one or two stars with an average score of 4.22 but also a sticker price of $320pp.
* - **
One and two star restaurants are indistinguishable - tabelog rating wise - with both categories scoring approximately 3.89. However, two starred restaurants cost $250pp while one star restaurants cost only $166pp, which should teach us that each michelin star is worth about $70-$80 but that you get nothing in terms of quality with the second star.
Finally, in line with this observation, Bib Gourmand places cost an average of $75 and score 3.6 on tabelog.
In each category there are some clear errors by michelin, and the standard deviation is high enough that you can safely make the statement that:
Michelin agrees with Tabelog voters when it comes to the best and most expensive restaurants, but below that level it seems to generally offer mostly the assurance of higher prices for additional stars.
p.s. The high spend is just arbitrarily set to 50000 in the high end places.
